销轴联接的约束处理一直是液压支架试验有限元分析中的难点,本文主要分析对比了ANSYS目前的几种处理方式,既粘结、约束方程以及耦合自由度。并提出了把销轴联接当作接触分析,取得良好的效果。
The restraint of pin coupling has always been a difficult point in the finite element analysis of hydraulic support test. This paper mainly analyzes and compares the current processing methods of ANSYS, such as bonding, constraint equation and coupling degree of freedom. And put forward the pin connection as a contact analysis, and achieved good results.
