腰子形薄壳在内压作用下内力和变形的一种实用计算方法

A Practical Calculating Method on Internal Force and Deformation Kidney Thin Shell Caused By Internal Pressure

本文利用对称性、能量原理和板条梁对“腰子形薄壳”的计算进行简化,给出了“腰子形薄壳”在内压作用下内力和变形的一种实用计算方法。该方法避免了求精确解的繁冗计算,具有一定的精确性,能满足工程初步设计的要求。

This paper uses symmetry, plate spline beam and energy principle to simiplify the calculation of 'kidney thin shell'. A practical calculating method on internal force and deformation of the shell is introduced, which are caused by internal pressure. This method avoids the heavy and complicated calculation of exact solution and provides a higher accuracy. The method can well meet the needs of engineering design.
