摘要
以实验研究为基础,通过对大量实验结果的分析,借助于金属元件抗拉弹性模量和剪切模量的计算方法,推导出环形金属橡胶隔振器在承受扭剪应力时,抗拉弹性模量以及扭剪弹性模量与金属丝直径、环形隔振器的几何参数、金属橡胶元件的相对密度之间的关系的理论计算公式。研究结果证明,利用该计算公式和有限元计算方法,可以直接求得具有不同结构参数的相应形状金属橡胶隔振器的弹性性能参数,所得计算结果与实验结果具有良好的一致性,因而大大减少了实验工作量,为金属橡胶隔振器的系列化生产奠定了基础。
Based on an experimental research and a calculation method of tensile and shear elastic modulus, the equations of relationship of tensile elastic modulus and shear elastic modulus with diameter of metal wire, parameter of vibration isolator and relative density of metal rubber (MR) element were obtained by the analysis of experimental results. It is proved that, by the help of these equations and finite element method, it is possible to calculate directly the elastic properties of ring-like MR vibration isolator of different diameters. The comparison of experimental results and calculated results is good, it reduces the experimental working time and is helpful to design new types and new series of ring-like MR vibration isolators.
