| 摘 要： | 有限元分析是发动机隔振橡胶元件设计开发的现代分析方法.橡胶元件的形状系数对其外在弹性特性影响的复杂性、动一静刚度比的多样性及黏弹性阻尼特性是其工程应用方面的难点.系统研究了橡胶有限元分析在工程应用上需要明确回答的问题,指出橡胶有限元分析的材料数据应是消除端部摩擦后的圆柱压缩试验数据,超弹性本构模型能够反映橡胶元件的静特性以及橡胶作为有质量弹性体对其动特性的影响规律,黏弹性本构模型能够反映橡胶元件的阻尼特性,但两种本构模型均不能反映其动一静比特性.如何准确反映橡胶元件的动-静比特性是橡胶有限元分析的重要课题.

| Abstract: | Finite element analysis(FEA) is an advanced method in the development and design of automotive rubber components.The complexity of elastic characteristics influenced by rubber component shape factor,the variety of static-dynamic ratio,and the damping of the rubber component lead to the difficulties of rubber FEA in engineering applications.The above three factors are studied and the results indicate that the FEA input data of the rubber material should be the test data when the frictions at two ends of the ... |
