【摘要】 本文分析了几个航炮零件在运动渐变状态工作过程中取得的计算载荷。然后对这些零件进行有限元法和光弹法的应力分析,并对它们的结果进行了对比研究。为了核对,对一些点取得了电测应力的数值。几种情况所得结果比较一致,表明结果是可信的;这种用有限元法和光弹法结合起来,研究武器构件的应力分布规律的方法,是值得推荐的。更多还原

【Abstract】 This paper analyses the calculated loads sustained on some aerial gunelements in its operating process in motion transition state. Then the stressanalyses for these elements by finite element method and photoelasticmethod are made, and the results obtained are scrutinized through compar-ison. In order to check the results, the values of stress are electricallymeasured for some points The results obtained for some cases are compar-atively compatible, which shows that the results are believable, andthe way for study of the stress distribution law of weapon members bycombination finite element method with photoelastic method is recommend-able.更多还原
