摘要: (Ⅲ)是(Ⅰ)的具体应用.计算了C型波纹管的角向刚度、横向刚度和相应的应力分布.将波纹管的凸面和凹面分开处理,分别应用一般解(Ⅰ),使连接点满足内力和变形连续性条件.所得结果与相应的数值积分解、其它理论解及实验进行了比较.结果表明,中细柔性圆环壳的方程和一般解(Ⅰ)准确可信.Abstract: This is one of the applications of Part(Ⅰ),in which the angular stiffness,the lateral stiffness and the corresponding stress distributions of C-shaped bellows were calculated. The bellows was divided into protruding sections and concave sections for the use of the general solution(Ⅰ),but the continuity of the stress resultants and the deformations at each joint of the sections were entirely satisfied. The present results were compared with those of the other theories and experiments,and are also tested by the numerically integral method. It is shown that the governing equation and the general solution(Ⅰ) are very effective.
