加筋球冠结构在静动载荷作用下的动响应分析

借助ANSYS/LS-DYNA程序,分析加筋球面艏端隔壁在静动载荷作用下的动响应,求得了静动载荷作用下的球面艏端隔壁结构的动力响应;分析潜艇发射雷弹时发射管的转角变形,给出了潜艇发射雷弹时发射管转角变形的规律。分析时选用顺序求解法,即借助ANSYS对艏端隔壁结构进行静力分析,将其结果作为艏端隔壁结构动力作用下的初始条件,然后再借助LS-DYNA进行艏端隔壁结构的动力响应分析。通过大量的数值实验,并结合理论分析,最终给出了潜艇发射雷弹时发射管的转角变形规律。

Dynamic Response Analysis on Spherical Stem Bulkhead with Ribs under Hydrostatic and Dynamic Loads

Dynamic response analysis on submariners spherical stem bulkhead with ribs under hydrostatic and dynamic loads when launching torpedoes is carried out with ANSYS/LS-DYNA, and the dynamic response of submariners spherical stem bulkhead is obtained in this paper. At the same time, launch tubers angular deformation is studied when launching torpedoes at certain depth, and a calculation formula of launch tubers angular deformation is also obtained. The analysis method is that static analysis of submariners spherical stem bulkhead with ribs is firstly obtained by ANSYS, and then the result is used as initial condition to calculate structurers dynamic response. Numerical experiments and theoretical analysis are performed and the relationship of launch tubers angular deformation is also considered. The results obtained by numerical experiments and theoretical analysis are compared with experimental results.
