Now a days vehicle became a basic need of human hence the production of vehicles as well as demand of vehicles are increasing. Hence number of vehicles on road are increased. Therefore accidents are increasing. One of the best way to minimize the accidents is to install the speed breakers in front of school, hospital, temple, railway crossing etc. Due to speed breaker rider maintain minimum speed and chances of accidents are reduced. Speed breaker oppose the vehicle and impact force is created in suspension system. By using impact force power is generated with the help of dynamo and alternator. The generated power is used to charge the battery. About 100- 400 watts power is generated with the help of middle size vehicles like car, taxies etc. Key words: Speed breakers, Impact Energy , Regenerative suspension system, Alternator, Dynamo and Battery 1. INTRODUCTION The number of vehicles are travelled on a road. The road may be rough or smooth. On rough road more vibrations are created as compare to smooth road. These vibrations are not used for any purpose and vibrations are wasted. Vibrations are commonly wasted in forms of thermal energy.. By using regenerative suspension system 100-400 watts average power is generated with the help of middle size vehicles. Middle-size passenger vehicle needs 180 to 200 watts power for various processes like fuel ignition and injection processes. Also the middle size vehicles requires 250 to 260 watts power for lighting system like head light, front light, main lamp etc. The total need of power of middle size vehicles for various requirement is about 180 to 400 watts. By using regenerative suspension system it is possible that to charge the battery of vehicle. Therefore load on the vehicle engine is reduced and the requirement of fuel is reduced at certain level. Thus by using regenerative suspension system charging of battery as well as fuel consumption is reduced.[5] 2. LITERATURE SURVEY Larry Weng ,Geoff Walker et.al[1] have researched on energy storage system for regenerative dynamometers. In this paper, various types of dynamometers have been researched. One of those is regenerative dynamometer. In this mechanical energy is converted into electrical energy for charging the battery. Zhang Jin-qiu, PengZhi-zhao et.al[2] studied on energy conversion system in suspension system. The regenerative suspension systems have attracted much attention in recent years for the improvement of vibrating attenuating performance and reduction of energy dissipation. Jun Yin ,Xinbo Chen et.al[3] have researched on how to design and analyze regenerative suspension system. From this paper we come to know that how to design the kinematics of this system. To achieve better suspension performance. The regenerative suspension system should be controlled in consider of the kinematics and dynamics of the system. The advantage of regenerative suspension system is demonstrated by comparison with suspension performance of passive suspension system. MohdAzman Abdullah , JazliFirdausJamil et.al[4] have studied and developed a device to harvest vibrational energy . Based on the frequency and amplitude of potential vibrations a device is designed and developed. This device is further assembled in a passenger vehicle.[4] 3. OBJECTIVES 1.
