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
The bulb tubular shell has some stability problems under water pressure. This paper shows that the critical pressure of beam-column instability can be calculated by a limit stress function, and the limit stress function is expressed in dimensionless form Therefore, the problem of calculating the stability of the spherical shell structure can be solved by the model experiment principle. At the same time using the finite element method of stiffness analysis
