中文摘要: |
外压薄壁圆筒水密舱在工况条件下能够安全承压的必要条件是构件具有足够的强度和刚度,否则构件加载后将分别发生屈服破坏和失稳.其他条件不变时构件的临界长度决定了失稳临界压力大小.因此,工程设计前首先要对构件强度和刚度进行研究和仿真. |
英文摘要: |
For a thin thickness cylinder cabin under external pressure, it is essential in the normal condition to ensure the components of the cabin having enough strength and stiffness. The components under the normal pressure will yield if no enough strength and they will buckle if no enough stiffness. The critical lengths of the components decide their critical pressures when the components keep in original conditions. Therefore, it is right and necessary to research and to simulate strength and stiffness of the components first, and then to get the theoretical basis for engineering design. |
