R12制冷压缩机改用R22时的强度分析

The Strength Analysis of Using R22 instead of R12 in Refrigerating Compressor

对８ＦＳ７压缩机机体进行了强度分析，通过应力测试、有限元计算、爆破试验与断口分析，指出了该压缩机改用Ｒ２２时的薄弱部位，提出了改进措施。

The strength of 8FS7 compressor case isstudied. Through the measure of stress,computerization of finite element, explodingtest and analysis of fragment, the weakposition of the compressor which used R22is indicated and the improving method areproposed.
