摘　　要：通过与经验公式法对比,总结有限元技术辅助进行橡胶悬置正向开发的优势;以Abaqus有限元软件为基础,阐述如何应用有限元技术进行橡胶悬置正向开发流程;依据流程,介绍了两例橡胶悬置正向开发案例。结果表明,有限元技术辅助设计的橡胶悬置不仅达到了刚度目标要求,而且强度、寿命大幅提高,同时产品开发周期有效缩短。Comparing with empirical formula, the advantages of FEM aiding forward design of rubber mounting is summarized in the paper. And based on the FEM software Abaqus, the process is presented in details on how to conduct the rubber mounting forward design. Then, the two cases of the forward design of rubber mounting are introduced. The results indicate that the designed rubber mounting using FEM can not only meet the stiffness requirement, but also improve the strength and fatigue life significantly, and the development cycle is shortened greatly.
