前言某些轴对称另件(如厚壁园筒)的过盈配合应力计算问题,早就有成熟的理论解答。若相配的两个另件之一或二者均为非轴对称结构,则过盈配合引起的应力,只能通过实验方法或有限元计算方法来求解。考虑到此类问题在机械制造专业中的普遍性,本文以西南仪器厂某另件(非轴对称结构)的过盈配合为例,介绍光弹模型试验及有限元计算方面的特点。关于此类问题的有限元分析,迄今能看到的参考资料还很少,我们的
Foreword Certain axisymmetric components (such as thick-walled cylinder) with the interference stress calculation problems, there are already mature theoretical solutions. If one or both of the two mating parts are non-axisymmetric, the stress caused by the interference fit can only be solved experimentally or by finite element method. Taking into account the universality of such problems in the field of mechanical manufacturing, this paper takes the interference fit of another piece (non-axisymmetric structure) of Southwest Instrument Factory as an example to introduce the characteristics of the photoelastic model test and finite element calculation. Finite element analysis on such issues, so far can see the reference is very small, our
