研究了一周边固定的扁薄锥壳在温度载荷和横向载荷共同作用下的过屈曲问题.利用数值计算的方法,得到了温度载荷?横向均布静载荷和扁壳横向大挠度位移的关系曲线,可以明显看出扁壳结构的平衡路径随载荷的变化存在跳跃现象,并给出了一个特殊情况可能存在的几种不同的过屈曲构形.
The problem of over-buckling under a combination of temperature load and lateral load is studied. The relationship between temperature load, lateral uniform static load and lateral large deflection displacement is obtained by means of numerical calculation , It can be clearly seen that the equilibrium path of the flat shell structure jumps with the change of load and gives several different kinds of over-flexion configurations that may exist in special cases.
