摘要: 在鱼雷方案设计阶段, 为降低结构振动传递响应, 优化设计参数, 采用有限元法, 建立了基于Work- bench的鱼雷结构参数化等效模型。以某型鱼雷为例进行全雷结构响应谱分析, 以减小振动传递响应为目标, 优化等效集中质量、壳体厚度、矩形截面加强筋尺寸等结构设计参数。仿真结果表明, 该参数化等效模型能有效仿真鱼雷结构振动传递特性, 结构经优化后自导头段振动传递响应有所降低。Abstract: For reducing structural vibration transfer response and optimizing design parameters in the scheme design phase of a torpedo, finite element analysis is employed to establish a parameterized equivalent model of torpedo structure based on Workbench. Response spectrum analysis is conducted for the shell of a certain type torpedo. The design parameters, like equivalent concentration of mass, shell thickness, and size of reinforcing rib with rectangular cross section, are optimized to reduce the vibration transfer response. Simulation results show that this parameterized equivalent model can effectively simulate the characteristic of structural vibration transfer of a torpedo, and the vibration transfer response of the homing head cabin decreases after optimization.
