摘要

摘要: 针对雷-靶碰撞过程中靶体结构及碰撞环境的特殊性与复杂性, 基于船舶碰撞内部机理, 采用流固耦合及附加质量法对鱼雷撞击目标靶时的结构响应进行了有限元仿真, 研究了碰撞过程中靶体的结构损伤以及鱼雷速度及加速度变化。仿真结果表明: 1) 撞击过程具有很强的非线性特征, 撞击角度的变化对雷体运动及靶体变形有一定程度的影响; 2) 鱼雷撞击速度越大, 雷头加速度响应峰值越高, 靶体损伤程度越大。文中所做研究可为目标靶的结构设计及动态特性设计提供参考。

Abstract: In view of the particularity and complexity of target structure and collision environment in the collision process of a torpedo and a target, the internal mechanism of ship collision is utilized and the fluid-solid coupling and additional mass method are employed to carry out finite element simulation of the structural response of a torpedo when it hits a target. The structural damage of a target and the variation of torpedo velocity and acceleration during collision are studied. Simulation results show that: 1) The hitting process has strong nonlinear characteristics, and the hitting angle has a certain influence on the motion of a torpedo and the deformation of a target; 2) The higher the torpedo hitting velocity is, the higher the peak acceleration response of torpedo head and the damage degree of target become. This research may provide a reference for the structure design and dynamic characteristic design of targets.
