| 摘 要： | 捞雷具用于水下半埋状态实验鱼雷打捞.文中以水下半埋状态鱼雷打捞为研究对象,依据捞雷具工况初步确定了夹紧机构夹紧力,利用薄壳强度理论对鱼雷壳体的强度和稳定性进行了计算,证明了夹紧机构夹紧力的大小是适当的.并利用大型结构分析软件ANSYS,采用有限元方法,对鱼雷壳体的强度进行了计算.根据有限元法获得的计算结果与解析法计算结果相比较,验证了有限元法的可靠性.为捞雷具夹紧机构的结构设计和优化提供了理论依据.

| Abstract: | To salvage an experimental torpedo that was half-buried under water,the clamping force of a salvage device was determined according to the working condition of the device.The strength and stability of the torpedo hull were calculated using thin hull theories,and the clamping force was verified to be suitable.The strength and stability of the torpedo hull were also calculated by ANSYS structural analysis software.The reliability of the finite element method was verified by comparing the calculated results obtained from analytic method with the calculated results obtained from finite element analysis method.The findings provide a theoretical basis for structure design and optimization of clamping mechanisms. |
