摘要
橡胶具有较好的阻尼效应，所以橡胶在隔振元件中应用最为广泛。为了有效地设计出具有所需特性的橡胶隔振器，必需了解隔振器在各种载荷条件下的力学特性。由于橡胶材料具有强烈的非线性特性，橡胶体在隔振元件中的几何形状复杂，使得几乎不可能求出其动态特性的解析解，为此，必须求助于一种有效的数值解法，而非线性有限单元法正是解决此类问题的最佳方法。
Rubber is widely used in vibration isolators due to its advantage of damping. In order to design desired rubber vibration isolators efficiently, it is necessary to study its mechanical properties under different loadings. Since rubber materials have strung geometry and physical nonlinearity, the geometry shape and boundary conditions of the rubber body in isolators are very complex. It is almost impossible to obtain its theoretical solution of its static or dynamic property. Therefore, a nonlinear FEA, which is an effective numerical method, is called to solve these problems.
