摘　　要：针对传统滚珠丝杠式机电惯容器换向时存在的惯性逆效应,提出一种可稳态切换的新型滚珠丝杠式机电惯容器设计方法。首先,介绍了新型机电惯容器的结构与工作原理,依据滚珠丝杠式惯容器与旋转电机的动力学模型,建立了机电惯容器的动态模型;其次,基于新机电相似理论,仿真分析外接不同电容下的机电惯容器力学性能输出,研究电机电感与电阻对力学性能输出的影响规律;最后,对比传统机电惯容器与稳态切换式机电惯容器,分别在有、无外接负载的工况下进行力学性能测试。结果表明,稳态切换式机电惯容器可以较好地减小飞轮换向时对丝杠的惯性冲击,验证了设计方法的有效性。Aiming at the inverse effect of inertia existing in the reversing of traditional ball-screw mechatronic inerter,a design method of stable switching ball-screw mechatronic inerter is proposed.Firstly,tthe structure and working principle of the stable switching mechatronic inerter is introduced,and the dynamic model of the mechatronic inerter is established based on the dynamic model of the ball-screw inerter and the rotating motor.Secondly,based on the new mechanical and electrical equivalence theory,the mechanical performance output of the mechatronic inerter under different capacitance is simulated and analyzed,and the influence of the motor inductance and resistance on the performance output is studied.Finally,compared with the traditional mechatronic inerter and the stable switching mechatronic inerter,the mechanical properties are tested with and without external load.The results show that the stable switching mechatronic inerter can reduce the inertial impact on the lead screw when the flywheel changes direction,which verifies the effectiveness of the design method.
