【摘要】 灯泡贯流式发电机迎水球壳在水压作用下存在稳定性问题 ,本文说明 ,梁柱失稳时的临界压力可以用一个极限应力函数来计算 ,而极限应力函数是用无量纲的形式表达的 ,所以计算球壳结构的稳定性问题可以用模型实验原理解决。同时利用有限元法进行了刚强度分析更多还原

【Abstract】 The Bulb Hydrogenerator sphere shell exist stability problem during hydraulic pressure.This paper indicates that critical pressure is calculated by a limit stress function,moreover,this function expresses is dimensionless so that calculating stability of sphere shell structure can be solved by principle of model experiment.At the same time,the analysis of rigidity and intensity is completed by FEM method.更多还原
