摘要
提出了一种直线电机与可调阻尼减振器集成的车辆悬架振动能量回收方案,设计了可以将振动能量转化为电能的半主动悬架馈能器(SASR),基于圆柱坐标系对SASR用筒式永磁直线电机进行了解析分析,并与基于Ansoft的有限元结果进行对比,解析结果与有限元仿真结果吻合,验证了解析计算方法的正确性。在此基础上,探讨了电机工作速度和永磁体长度对SASR馈能特性的影响,确定了使SASR馈能性能达到最优的永磁体长度。最后,分析了SASR在随机路面激励下的馈能效果,验证了回收悬架振动能量的可行性。
A scheme design is presented to reclaim vehicle vibration energy by integrating linear motor into the adjustable shock absorber. Semi-active suspension regenerator （SASR） which could convert vibration energy into electrical energy is designed. Based on cylindrical coordinate system, a kind of analytical method is introduced to analyze numeric field of tubular permanent-magnet linear motor used in SASR. Compared with the result of Ansoft based finite simulation, the proposed method is confirmed. On this basis, the effect of the motor velocity and permanent magnet length on energy- regenerative performance of SASR is analyzed. And the optimal permanent magnet length is determined. Finally, energy- regenerative performanee under random road excitations is simulated. The result validates the feasibility of suspeasion energy- re ge ne ration.
