Design of Novel Energy Recovery Damper Based on EAP

Damper is an important part of vehicle suspension system, containing the nonlinear vibration system of elastic force and damping force, this system generates vibration excited by road irregularities and vibration source such as engine. To solve shortcomings of the traditional vehicle that consumes energy high and wastes the vibration energy, in this paper, through analyzing the existing principle of vehicle vibration energy recovery and power generation mechanism of electroactive polymer (EAP), integrating both advantages, design a novel energy recovery damper based on EAP, draw three-dimensional maps and two-dimensional maps of novel energy recovery damper and suspension system with Solidworks software, and do the simulation study about the vibration power generation process of this damper. It can be achieved to recycle the car body vibration energy through the vibration energy recovery damper, translate the kinetic energy of the car body vibration into electrical energy to charge the vehicle battery, so as to reduce the waste of energy, save energy and improve energy efficiency.
