seminars report on power generating shock absorber - SONIA - 10-04-2017
Abstract
During the everyday usage of an automobile, only 10 16% of the fuel energy is used to drive the car to overcome the resistance from road friction and air drag. A conventional automotive shock absorber dampens suspension movement to produce a controlled action that keeps the tire firmly on the road. This is done by converting the kinetic energy into heat energy, which is then absorbed by the shock s oil. This is the important loss is the dissipation of vibration energy by shock absorbers in the vehicle suspension under the excitation of road irregularity and vehicle acceleration or deceleration. In this paper we study the concepts of power generating shock absorber which can efficiently recover the vibration energy in a compact space.
Power generating shock absorber absorber is a device that converts the kinetic energy of an oscillating object into electric energy. This kinetic energy is normally dumped in a form of thermal energy in a conventional, mechanical shock absorber. It consists of a permanent magnet linear synchronous generator (PMLSG), a spring, and an electric energy accumulator. The major goal of the project is to design and analyze the operation of an electric shock absorber. It is successfully tested on electric vehicles. The system performs best on heavy, off-road vehicles moving quickly over rough terrain.The shock absorbers are connected to a power management system that can interface with other sources of power, such as regenerative braking systems, thermoelectric devices that can convert waste heat into electricity.
