| 摘 要： | 将海德福斯螺纹插装换向阀集成到压电叠堆电静液作动器中,形成一体化集成式双向运动的压电叠堆电静液作动器。基于压电叠堆电静液作动器的物理系统,采用Simscape搭建压电叠堆电静液作动器系统模型。对比了在不同蓄能器偏压、不同电压峰值条件作用下,压电叠堆电静液作动器的实验输出流量与仿真输出流量;以及换向阀换向周期为4s时,压电叠堆电静液作动器的实验输出位移与仿真输出位移,验证了搭建的Simscape模型的准确性。在系统模型得到验证的基础上,分析发现阀片的回流现象是造成压电叠堆电静液作动器在高频驱动时输出流量衰减的原因。

| Abstract: | An integrated bidirectional motion piezoelectric stack electro hydrostatic actuator (PEHA) has been realized by integrating the Heidelfos thread insertion valve into the piezoelectric stack electro-hydrostatic actuator (PEHA). Based on the physical system of PEHA, the PEHA model has been established by using the Simscape. The experimental output flow and the simulated output flow of the piezoelectric stack electro hydrostatic actuator are compared under the conditions of different accumulator bias and different voltage peak conditions. The experimental output displacement and the simulated output displacement of the piezoelectric stack electro-hydrostatic actuator are also compared when the reversing valve period of the reversing valve is 4 s. The accuracy of the Simscape model is verified. Based on the verification of the system model, it is found that the backflow phenomenon of the valve plate is the cause of the attenuation of the output flow of the piezoelectric stack electro hydrostatic actuator at high frequency driving. |
