Design and Testing of Regenerative Suspension System

With the increasing number of vehicle possession and severe hike in consumption, natural fuels which are obviously limited and on the verge of extinction, the area of energy conservation and saving have received great attention from automobile manufacturers and the government all over the world. Usually the vibration energy caused by road roughness when the runs have not being paid attention to and it is wasted through conversion to thermal energy. If the vibration energy can be recovered and converted to other form of energy so as to supply for other devices then the aim of eco-friendly energy saving is reached. This paper consists design and analysis of mechanical regenerative shock absorber in detail. The mechanism of this innovative shock absorber implies use of a simple D. C generator for the conversion of energy possessed by the relative motion between vehicle wheels and the chassis. At the same time, the damping can remove the discomfort caused by the irregular road surface. The regenerated electric power can be recovered through the battery. The analysis of N-66 gears used in the system for lower inertia and better performance was performed on the ANSYS software based on the structure parameters as found by the design calculations. Analysis and calculations prove the viability of this shock absorber.
