E-ACE (acrylic elastomer) is a kind of material so far in electro-active polymer (EAP) in the most excellent performance. Based on the analysis of the basic principle of the E-ACE power generation, the feasibility is studied on E-ACE power generation principle to achieve energy recovery and damping. Design a model damping device of vehicle for energy recovery based on E-ACE. Through analysis, when the system vibrates near the resonance frequency, deformation of spring is greater, E-ACE materials to move up and down reach the larger amplitude, and the more energy it produces. To analysis the system about harmonic response by ANSYS software, get the relationship between spring stiffness K, damping coefficient C and external incentive, then analysis the resonance frequency of the system. The simulation results verify the feasibility of the design scheme. Results show that E-ACE has excellent performance in the automobile vibration energy recovery and vibration. E-ACE will have broad application prospects.

In order to promote the efficient recovery of the vibration energy, to achieve the purpose that energy of vibration can be converted to electrical energy and implement the vibration energy recovery, the electroactive polymers (EAPs) were discussed and studied in this paper. The vibration power generation mechanism of EAPs and vibration system were theoretical analysed, a nonlinear technology (synchronized switch harvesting with inductor) was used in process of energy recovery. The experimental results showed that EAPs had good effect of the vibration energy conversion and nonlinear technology was more efficient than conventional technology in energy recovery.
