There is need for the efforts in order to use the energy efficiently& effectively. Every day million of vehicles run on the road which creates the possibility to utilize impact force exerted by them on the road. In this project an effort has been taken to utilize the force into energy form which is exerted by the vehicles and is available in huge amount. CHAPTER: .1 INTRODUCTION . In this project the above concept about the possibility of energy extraction is used & an effort is taken to formulate a prototype to convert such concept into reality. . energy consumption is directly related to the level of living population and industrialization of the country is increase. Today. in the present time with the drastic increase in the population of vehicles. Hence.1 INTRODUCTION In our day to day life the energy sources are diminishing with a drastic speed. Soon the day will come when man has to rely on the non-conventional source of energy. We need to think about the extraction of energy from these vehicles without any effect on the normal routine of vehicle.CHAPTER: . Today it is the basic responsibility of a person to save as much energy as he can. Throughout the history of human race major advantage in the civilization has been accompanied by increase in consumption of energy. E.Energy extraction involves the principle of conversion of P. . It is designed and fabricated with respect to the vehicle load of range 750kg to 1500kg with a velocity of 15 to 20 km\hr. It is a model which has a mechanism connected with a speed breaker in order to absorb the impact force due to the passing of vehicles over a speed breaker.E into E. CHAPTER 2 PLANNING . .

CHAPTER 3 REVIEW OF LITERATURE . electrical equipment like motors. which is really static electricity moving toward you. Benjamin Franklin did not “invent” electricity. is simply a flow of electrons between the ground and the clouds. Greek Philosophers discovered that when amber is rubbed against cloth. but there have been many other inventors throughout history that were each a part in the development of electricity. lightweight objects will stick to it.CHAPTER 3 REVIEW OF LITERATURE 3. In fact. . The first discoveries of electricity were made back ancient Greece. Hence.1 History of Electricity:Depute what you have learned. The truth is that electricity has always been around because. light blubs. When you touch something and gets a shock. We’ve all heard of famous people like Benjamin Franklin and Thomas Edison. They are just creative inventions to harness and use electricity. and batteries isn’t needed for electricity to exist. This is the basis of static electricity. Over the centuries. there have been many discoveries made about electricity. electricity did not begin when Benjamin Franklin at when he flew his kite during a thunderstorm or when light bulbs were installed in houses all around the world. 1 HOW IS ELECTRICITY GENERATED? Transmission line for long distance Street light Transformer step up Voltage for transmission Neighborhood transformer step down voltage The electricity is generated by any of the following devices which work on Faraday’s Law.Dynamo GENRETOR .3. .Generator . and a set of rotating windings which turn within that field. The process is based on the relationship between magnetism and electricity. something causes the shaft and armature to spin. The spinning magnet was positioned so that its north and south poles passed by a piece of iron wrapped with wire. It used a permanent magnet which was rotated by a crank. When a wire or any other electrically conductive material moves across a magnetic field. The dynamo uses electromagnetic principles to convert mechanical rotation into an alternating electric current. larger machines have the magnetic field created by electromagnets.An electric generator is a device for converting mechanical energy into electrical energy. a French instrument maker. In a generator. The first dynamo based on faraday’s principles was built in 1832 by Hippolyte Pixii. . A generator produces electricity. an electric current occurs in the wire. A dynamo machine consists of a stationary structure which generates a strong magnetic field. An electric current is generated. as shown in the picture (lighting bolt) DYNAMO:- The Dynamo was the first electrical generator capable of delivering power for industry. On small machines the magnetic field may be provided by a permanent magnet . energy cannot be readily restored to the battery by electrical means. .2 BATTERY This generated electricity can be stored for future use in the form of charge in the device known as battery. Primary battery . Once the initial supply of reactants is exhausted. Classification of batteries Batteries are usually divided into two broad classes: .3. Secondary battery Primary batteries irreversibly transform chemical energy to electrical energy. restoring their original composition. Secondary batteries can have the chemical reactions reversed by supplying electrical energy to the cell. 3.3 MECHANICAL COMPONENT (RELATED TO PROJECT) a) CHAIN DRIVE . CHAPTER 4 DETAIL OF PROJECT . .

Cost of GLS is 2500/. It consumes very much power. Cost of GLS is 2500/.Rupees.This provides light with the amount of heart i. current gives more heat and then it produce more light.e. Due to hear process the power consumption is more just like GLS. And these are made with the help of chromium & tungsten. Bulb used in street lights in India are as follows:GLS (gas filled lamp) Halogen GLS (Gas Filled Lamp) :. Halogen :. Rupees. But we take 500 bulbs in 1 kilometer 1 bulb 500 bulbs = = 100 watt 500 x 100 . In 1 Kilometer (30 poles) are required in 1 pole we use 5 bulb so in 30 poles it required 150 bulbs. Mirror :. Spreading of light depending upon dot of mirror (silver ammonium polish) Note: In CFL electric circuit watt reduces but current will increase it consume 10 times less current then other bulb as compare to halogen bulb. Per bulb gain 250 volts. Rating on a street light for: Halogen and GLS 500 watt of each bulb in one Kilometer 60 bulb wants but we take 100 bulbs.But in our project we use CFL (compact florescent lamp) this is also called critically low power filament circuit which develop less hear with more light that is known as florescent tube(FTL).In our project highly polished mirror is used are used. 1 Bulb 100 Bulb = = 500 watt 50000 watt or 50 kw = = 250Amp 5 lac The current required = 50000/250 So dynamo required 200 Amp / 50kw Cost of 50 kw and 200 Amp Dynamo or it required speed 1440rpm to 3500rpm For CFL we know that electric current CFL (100 watts) required 10 times less than in comparison to Halogen. Due to this process consumption of power is less both the corner tungsten wire is provided which develop florescent in the meaning of light. Cost of CFL is 100/. but also allows for accurate model calculations. This not only facilitates the creation of realistic geometry. Pro/ENGINEER models the complete solid. Pro/ENGINEER provides mechanical engineers with an approach to mechanical design automation based on solid modeling technology and the following features. such as those for mass properties. Other 3-D modelers represent only the surface boundaries of the model. feature based. 50/10 Current required = = 5kw = 50000/250 X 10 20 Amp 50000/250 X 10 Volt required for bulb 50000 = = 20 Volt Heating of electricity for 1 bulb halogen bulb for 10 hours. . 500 watt X 1 Hours = 5000 watts In 1000 watts = 1 unit = 10 Rupees Introduction to Pro/E Wildfire 4.0 Pro/ENGINEER is a parametric. 3-D Modeling The essential difference between Pro/ENGINEER and traditional CAD systems is that models created in Pro/ENGINEER exist as three-dimensional solids.= = 50000watt 50 kw we know that CFL used 10 times less electric in comparison to Halogen. solid modeling System. It is the only menu driven higher end software. distance.Parametric Design Dimensions such as angle. When you modify the dimensions. CAD Geometry of Electric generation-Mechanism . You can create relationships that allow parameters to be automatically calculated based on the value of other parameters. the entire model geometry can update according to the relations you created. and diameter control Pro/ENGINEER model geometry. a hole has a diameter. and placement. Each features asks the user for specific information based on the feature type. These features have intelligence.Feature-Based Modeling You create models in Pro/ENGINEER by building features. in that they contain knowledge of their environment and adapt predictably to change. depth. . while a round has a radius and edges to round. For example. without penalty. Combining Features into Parts The various types of Pro/ENGINEER features serve as building blocks in the progressive creation of solid parts. at any point in the development cycle.Associativity Pro/ENGINEER is a fully associative system. including assemblies. This means that a change in the design model anytime in the development process is propagated throughout the design. This intent is achieved by establishing feature and part relationships and by the feature-dimensioning scheme. The concept of capturing design intent is based on incorporating engineering knowledge into a model. automatically updating all engineering deliverables. and manufacturing data. Capturing Design Intent The strength of parametric modeling is in its ability to satisfy critical design parameters throughout the evolution of a solid model. drawings. Certain . An example of design intent is the proportional relationship between the wall thickness of a pressure vessel and its surface area. which should remain valid even as the size of the vessel changes. This enables downstream functions to contribute their knowledge and expertise early in the development cycle. Associativity makes concurrent engineering possible by encouraging change. The features that follow rely on the previously defined features for dimensional and geometric references. features can exist without children. Part Modeling • Starting Out in Part Mode--Describes how to start creating a part with Pro/ENGINEER. The following figure illustrates the progressive design of features. precede others in the design process.features. When a parent feature is modified. by necessity. This kind of relationship is termed a parent-child relationship. Because children reference parents. . its children are automatically recreated to reflect the changes in the geometry of the parent feature. but children cannot exist without their parents. Parent-Child Relationships The definition of a feature frequently relies on dimensional and geometric cues taken from another feature. The progressive design of features can create relationships between features already in the design and subsequent features in the design that reference them . It is therefore essential to reference feature dimensions and geometry so design modifications are correctly propagated throughout the model. The parent-child relationship is one of the most powerful aspects of Pro/ENGINEER. and Advanced Features --Describes how to create sweeps. . Patterning Features--Describes how to pattern features.

Assembly mode in Pro/ENGINEER enables you to place component parts and subassemblies together to form assemblies. use the File menu to open or create an assembly file (see Introduction to Pro/ENGINEER for more information). You must unexplode it first. You cannot attach components to an exploded assembly. you can also combine parts into assemblies. Attach a component nonparametrically using the Package command in the COMPONENT menu. Overview To create a subassembly or an assembly. You can add components to an assembly in the following ways: • • Attach a component parametrically by specifying its position relative to the base component or other components in the assembly. The ASSEMBLY menu displays the following options: • Component--Manipulates assembly components (using the COMPONENT menu). then finalize its location with assembly instructions. Use packaging as a temporary means to include the component in the assembly. • Create a part or subassembly directly in Assembly mode.Assembly Just as you can combine features into parts. Working with Assemblies To work with an assembly. analyze. Feature--Manipulates assembly features (using the ASSY FEAT menu). You can then modify. or reorient the resulting assemblies. you must place a base component or feature. then attach additional components to the base and to each other. as well as to design parts based on how they should fit together. This option is available only if you have a Pro/ASSEMBLY license. • . moving components from one assembly or subassembly to another (using the RESTRUCTURE menu).

Placing a Base Component If you do not create three orthogonal datum planes. As with an assembled base component. creating a flexible design. If you replace a base component with interchangeable components. The initial assembly units are the same as the units of the base component. or create a base component. you can assemble a component with respect to these planes. In many ways it is like the base feature of a part. or skeleton model placed into an assembly. You can reorder subsequent components to come before the first one (if the components are not children of the first component). the base component is the first part. you can either create an empty component or copy from an existing component. subassembly. When a base component is the first object in an assembly (before any assembly features). no placement constraints are defined. the initial assembly units are the same as the base component. The component is simply placed by default. you must either create three orthogonal datum planes as the first feature. Datum Planes as the First Features When you create three orthogonal datum planes as the first features in an assembly.Initial Procedures To place a base component or feature. Creating a Base Component When you create the first component of an assembly. and . You can replace the first component with interchangeable components. or skeleton model). or create a part in Assembly mode as the first component. You can pattern the first component you add. subassembly. the replacing components will always be placed by default as well. Using datum planes as the first feature has the following advantages: • • • • You can redefine the placement constraints of the first assembled component. interchange components that replace the created base component will always be in the default orientation. This is called parametric assembly. For more information about the Model Tree Window. Assembling a Component Parametrically You can position a component relative to its neighbors (components or assembly features) so that its position is updated as its neighbors move or change. . You can access this dialog box through either the pop-up menu in the Model Tree window or the Assemble command in the COMPONENT menu. use the Component Placement dialog box. To assemble a component parametrically. For more information on creating a base component. Pro/ENGINEER allows you to specify constraints to determine how and where the component relates to the assembly. and adjusting a component once you have placed it in the assembly.

The annual saving of electricity will be 523. From the test carried it is clear that the system can charge a battery within 4 hours and it can give a backup of about 4-5 hour.It can be used for Charging batteries and using them to light up the streets.Pinion mechanism: This mechanism is most popularly used.e. It was found that at high rpm the battery gets recharged very fast i.602 KW per year if the system works at full efficiency for 8 hours per day. within 4 hours The power can supplied for approximately 4 to 5 hours to the 20 watts fluorescent light tube. Principle of operation: Simple conversion from Mechanical energy to Electrical energy. any occurrence of variable load( which is bit obvious in case of vehicles!!) leads to balancing problem. . etc. It Generates electricity using the vehicle weight (potential energy) as input. This is because of the disadvantages of other mechanisms: Crank-shafts are required to be mounted on bearings which creates balancing problem leading to mechanical vibrations which in turn damage the bearings. The 3 different mechanisms proposed are: -Roller mechanism -Crank-shaft mechanism -Rack.Secondly as bearings are of sliding type. This can be done by implementation of the system on road which is busy running. .CHAPETER 8 FUTURE WORK The system can be modified to store a greater amount of energy to have a longer backup power.
