On the basis of the finite element analysis of the press - mounting machine , to solve the modeling error of the previous modeling method , a new mixed - model method using the spring element and thin - layer solid element was introduced in this thesis . an experiment designed to test the interface static stiffness was carried out and the needed modeling datum was obtained
在对压装机进行了整体建模仿真的基础上,针对压装机整体建模存在的误差问题,本文提出了一种改进的弹簧单元和薄层实体单元混合建模的方法,并依此设计了螺栓结合面静刚度测试试验,通过试验获得了建模所需的参数。
