Abstract

The snap fit is a common mechanical mechanism. We have studied the spherical snap fit carefully for its physical asymmetry, which is easy to assemble but difficult to disassemble. Because of the complexity of spherical snap fit, it is difficult to get a theoretical formula to describe its physical asymmetry. In this paper, the pushing assembly and pulling disassembly of spherical snap fit are studied by both finite element analysis and experiments. The theoretical formulaes of spherical snap fit have been obtained based on numerical simulations and theoretical results of cylindrical snap fit.

球形卡扣配合的装配和拆卸机制

卡扣配合是一种常见的机械机构。我们仔细研究了球形卡扣配合的物理不对称性，它易于组装但拆卸困难。由于球面旋合的复杂性，很难得到一个描述其物理不对称性的理论公式。本文采用有限元分析和实验相结合的方法，对球面卡箍配合的推装和拉拆进行了研究。在数值模拟的基础上，结合圆柱卡箍配合的理论结果，得到了球面卡箍配合的理论公式。
