POWER GENERATION FROM SPEED BREAKR
Abstract
It is a non conventional type of producing the energy. The existing source of energy such as coal, oil etc may not be adequate to meet the ever increasing energy demands. These conventional sources of energy are also depleting and may be exhausted at the end of the century or beginning of the next century. Consequently sincere and untiring efforts shall have to be made by engineers in exploring the possibilities of harnessing energy from several non-conventional energy sources. This project is a one step to path of that way. The overall goal was to design the speed breaker System while keeping the engineering, producer and customer models in check. The reason why this feature was used more than all of the other features are because the other features would not have as much effect on the complete system. By changing the size and desirable price, weight and capacity can be realized.
We used a survey to find out how the price, weight and capacity were scaled. Much was learned on how to and not to conduct a survey. A preliminary survey should have been conducted to determine a realistic value of variables. Also many of choices were not close enough together to get a reasonable cut off value. Therefore the data that was produced using conjoint analysis was most likely not as accurate as it could have been. Future work would consist of a redesign of this model to see exactly how much data we may be missing with the assumption that we made with low price, weight and capacity. Despite all the assumptions, we still have realized that this product can be very marketable and that the demand is extremely large which means this is a viable design that will yield a high return on an investment.
1.3 CRANKSHAFT MECHANISM:
The crankshaft is a mechanism that transforms rotary movement into linear movement, or vice versa. For example, the motion of the pistons in the engine of a car is linear (they go up and down).But the motion of the wheels has to be rotary. So, engineers put a crankshaft between the engine and the transmission to the wheels. The pistons of the engine move the crankshaft and the movement becomes rotary. Then the rotary movement goes past the clutch and the gear box all the way to the wheels.

Out of all these arrangements the rack and pinion arrangement has a higher efficiency than others so we chose to make a hybrid mechanism of it by using a hybrid technology to increase the development of power as compared to the conventional model.
Technical Details
While moving, the vehicles possess some potential energy and it is being wasted. This potential energy can be utilized to produce power by using a special arrangement. It is an Electro-Mechanical unit. It utilizes both mechanical technologies and electrical techniques for the power generation and its storage. This is a dome like device likely to be speed breaker.
Whenever the vehicle is allowed to pass over the dome it gets pressed downwards then the springs are attached to the dome is compressed and the rack which is attached to the bottom of the dome moves downward in reciprocating motion. Since the rack has teeth connected to gears, there exists conversion of reciprocating motion of rack into rotary motion of gears but the two gears rotate in opposite direction. A flywheel is mounted on the shaft whose function is to regulate the fluctuation in the energy and to make the energy uniform. So that the shafts will rotate with certain R.P.M. these shafts are connected through a belt drive to the dynamos, which converts the mechanical energy into electrical energy. The conversion will be proportional to traffic density. Whenever an armature rotates between the magnetic fields of south and north poles, an E.M.F (electro motive force) is induced in it. So, for inducing the E.M.F armature coil has to rotate, for rotating this armature it is connected to a long shaft. By rotating same e.m.f, is induced, for this rotation kinetic energy of moving vehicles is utilized.
The power is generated in both the directions; to convert this power into one way a special component is used called zener diode for continuous supply. All this mechanism can be housed under the dome, like speed breaker, which is called HUMP. The electrical output can be improved by arranging these speed breakers in series. This generated power can be amplified and stored by using different electrical devices.
