中文摘要：
由于混合隔振系统中的电磁作动器对电磁力、体积重量、损耗等指标有着严格的限制,因此电磁作动器的优化设计显得十分重要。为此,提出了电磁作动器系统参数（包括几何尺寸参数和电参数）的优化设计方法,推导了电磁作动器总损耗与系统参数间的关系。通过有限元分析软件ANSYS中的优化设计模块,使用ANSYS参数化设计语言建立了在保证电磁力及体积限制条件下,以总损耗最小为目标函数的三维参数化分析模型,多次循环迭代求解后得到了较为优化的系统参数。仿真及实验结果表明：按照该方法设计的电磁作动器能够满足各项设计指标要求,且性能比其他参数下更为优化。
英文摘要：
As the electromagnetic actuator is a key component of active vibration isolation system,so the optimal design of electromagnetic actuator is necessary due to strict limitation on electromagnetic force,volume,weight,and loss index.Thus,an optimal method for system parameters（including dimension para-meters and electric parameters） design for electromagnetic actuator was proposed and the relationship between total loss and system parameters was deduced.Based on the optimized mo-dule of ANSYS FEM software and ANSYS parameter design language,a three dimensional parameter analytic model which used the mini-mum amount of the total loss as object function was established under the limitations on electromagnetic force and volume.The optimal system parameters were obtained through multiple iterations.Simulation and experiment results show that the electromagnetic actuator designed with the method mentioned can meet the requirements of all the design targets and its performance is better.
