摘要
基于Donnell的非线性板壳理论,认为钢衬壳是一种有特殊缺陷形状的钢衬板,用初始后屈曲渐进分析理论,研究了在温度应力作用下缺陷钢衬板即钢衬壳的初始后屈曲性态。计算了一个四点铆固钢衬壳模型,同时给出了铆钉间距等参数对钢衬壳屈曲极值温度的影响。
Based on the Donned's nonliner theory of plates and shells, the initial postbuckling characteristics are investigated for the stud supported liner shells under thermal loads.Considering the liner shells as the liner plates with the cylindrical imperfection, asymptotic analysis of the initial postbuckling is performed An example is provided which shows the postbuckling stability of the liner shell and the validity of asymptotic predictions. The minimum postbuckling temperature of liner is also obtained.
