摘　　要：柴油机半主动隔振电磁作动器通过改变电流来改变作动器的刚度,达到柴油机减振目的。为了提高控制效果,要求作动器的位移和电磁力尽可能满足线性关系。在仿真研究电磁作动器的结构参数与位移-电磁力曲线关系,并经过实验验证后,一种具有良好线性特性的作动器结构被设计。With changing stiffness of a semi-active electromagnetic actuator vibration isolation throught adjusting its current, the purpose of deisel vibration isolation can be realized. To improve the contorl effect, the relation of displarement and electromagnetic force of actuator is requtred to be linear. After of the structure parameters of electromagnetic actuator and its relationship between displacement and electromagnetic force is simulateal, the simulation result is also verified by experiment. Thus, and electromagnetic actuator with gord linear dhamcter is designed.
