Study on Design Method and Performance of Electrostatic Hydrostatic Actuator Driven by Magnetostrictive Material

  • 摘要: M-EHA(Magnetostrictive electro hydrostatic actuator)是以GMM材料为驱动元件的一种适用于多应用场合的电静液作动器, 其性能影响因素较多, 理论分析较复杂。为能够对时间域下作动器的动态输出位移进行研究, 提出了一种新型的M-EHA的设计方法并研制了原理样机; 针对作动器试验测试过程中所涉及的相关要求, 对作动器相关结构进行了优化设计, 搭建了实验平台; 提出了一种新型的簧片阀腔体结构, 能够有效提高整个阀门性能; 设计了一种球头螺栓式预应力施加装置, 既保护了驱动单元, 又能够测试M-EHA在不同预应力下的输出性能; 在不同工作频率下对M-EHA的输出位移特性进行了试验研究, 在不同的偏置压力下对作动器的输出速度特性进行了试验研究。
