摘要

以大量试验数据分析为基础，提出了一种构建金属橡胶弹性恢复力三维模型的方法。通过对试验数据插值拟合处理与理论分析的方法，得到了恢复力关于位移和速度的二元解析方程，认为恢复力由线性正刚度弹性力、非线性阻尼力和与速度平方有关的非线性负刚度弹性力三部分组成，并对这三部分的实际物理意义进行了分析。试验结果表明，本模型对金属橡胶弹性恢复力的表述更加直观，分析更加准确，克服了现有模型简单和参数辨识复杂的缺点。

Abstract

Based on the analysis of a great deal of experimental data,a method of establishing three-dimensional dynamic model of restoring force of metal rubber is presented.Through interpolation fitting of experimental data and theoretical analysis,the analytic equation in which the relationship of velocity,displacement and restoring force is described is built.We consider that restoring force is composed of three components which are respectively linear elastic force with positive stiffness , non-linear damping force and non-linear elastic force with negative stiffness which is related to the square of the velocity.The physical meaning of the three components is analysed.Experimental results indicate that the proposed model can describe and analyse the restoring force of metal rubber more intuitively and exactly.The disadvantage that the present models are simple and the parameter identificating is complex is overcome.
