摘要

由于观察和试验的困难，越来越多的研究者采用有限元方法来模拟螺栓连接的松动过程。文中讨论了不同约束方法对结果的影响。结果表明，如果将两个结合部进行网格匹配，其结果与将两个结合部建模为一个部件的结果相同。如果两个绑定部分之间的网格不匹配，则结果与将两个部分建模为一个组件的结果有非常轻微的偏差。

The influence of constraint method on the finite element simulation for bolted joint

Due to the difficulty of observation and testing, more and more investigators use finite element method to simulate the loosening process of bolted joint. The influence of different constraint method on the results are discussed in the work. The results show that if the mesh is matched between the two tied parts, the results are the same as that of modelling the two parts as one component. If the mesh is unmatched between the two tied parts, the results have a very slight deviation from that of modelling the two parts as one component.
