无折边球形封头边缘附加弯矩及剪力简易计算

Simplified Calculations for Redundant Moments and Forces at Junctions of Spherical Segments and Cylindrical Shells in Pressure Vessels Subjected to Internal Pressure

本文在采用弹性力学薄壳理论进行分析的基础上提出两种受内压容器无折边球形封头与简体连接处附加弯矩及附加剪力的简易计算方法,可供工程应用。

Two simplified methods for calculating the redundant moment and the redundant force occuring at the junctions of the spherical segment and the cylindrical shell are proposed. The methods are based on analysis by using the thin shell theory of elasticity. The results from the simplified methods are found to agree with the theoretical solution with accuracies suitable for engineering applications.
