Design for Mechanical Structure of Energy Recovery Damper

Abstract

The traditional cars consume high energy and the energy of vibration is wasted. To solve these problems, a new energy recovery damper was designed by analyzing the principle of vibration energy recovery and the advantages of electroactive acrylic elastomer materials. The three-dimensional modeling was finished for the mechanical structure of the energy recovery damper. As an important constituent part of vehicle suspension system, the energy recovery damper was a nonlinear vibration system which contained elastic force and damping force. The system could generate random vibration with the drive of the sources such as pavement roughness and engine. The vibration energy can be recycled and stored into vehicle battery by the energy recovery damper. The energy could be saved by changing the vibration energy into electric energy. The energy recovery damper has the advantages of simple structure and high efficiency.

Design of Novel Energy Recovery Damper Based on EAP

“…As shown in Fig. 1, when the EAP is stretched, elastomer films will increase in the area decrease in the thickness to store energy, when the EAP is contractive and relaxing, to achieve electricity-generation [7][8][9][10].…”
