摘　　要：针对传统被动隔振器低频振动抑制性差的缺陷,设计了一种新型的电磁-橡胶主被动一体化隔振器,通过研究输出力特性来评估其减振性能,首先,利用等效磁路分析法对其磁路结构进行设计仿真以及动力学分析,并得到其电磁力计算公式。然后,基于COMSOL软件对作动器的输出力进行动态仿真分析,并得到电流及其频率对输出力特性的影响,最后,将特性实验结果与仿真结果进行对比分析。Aiming at defects of poor suppression of low frequency vibration for traditional passive vibration isolators,a new type electromagnetic-rubber active-passive integrated vibration isolator was designed.Its vibration reduction performance was evaluated through studying its output force characteristics.Firstly,the equivalent magnetic circuit analysis method was used to design and simulate its magnetic circuit structure,perform its dynamic analysis,and obtain its electromagnetic force calculation formula.Furthermore,based on the software COMSOL,dynamic simulation and analysis were done for the output force of the actuator to clarify effects of current and its frequency on output force characteristics.Finally,the characteristics test results were compared with simulation ones.
