摘　　要：以电磁变刚度支撑为研究对象,分析了随机变刚度支撑系统,介绍了该系统的工作原理。在此基础上建立了较为合理的线性化数学模型,为电磁变刚度支撑的结构设计提供了理论依据。同时通过有限元分析软件对电磁结构的电磁场特征参数进行了分析,并得出磁感应强度的分布图,为电磁变刚度支撑平台数学模型的修正提供了指导。Taking the electromagnetic variable stiffness support as the target of study, the supporting system of random variable stiffness was analyzed and the working principle of this system was introduced. On this basis the rather reasonable linearization mathe- matics model was established and provided theoretical basis for the structural design of electromagnetic variable stiffness support. At the same time an analysis was carried out on the electromagnetic field character parameters of electromagnetic structure by means of finite element analytical software. And the distribution diagram of magnetic induction intensity was obtained, thus provided guidance for the modification of mathematical model of electromagnetic varia- ble stiffness supporting platform.
