自航式实体模拟目标受鱼雷撞击冲击力计算仿真
|
摘要
本文采用有限元分析方法,构建某重型鱼雷、自航式实体模拟目标几何模型及参数,对鱼雷撞击自航式实体模拟目标的冲击力进行仿真计算,得出自航式实体模拟目标的变形以及塑性应变,为自航式实体模拟目标的安全防护设计提供技术支撑。
The geometric model and the parameters of the self-propelled entity target and the heavy torpedo is set up.Using the finite element analysis method, the impact is simulated when the torpedo strikes the self-propelled entity target point-blank. Through the deformation and the plastic strain of the self-propelled entity target. The solid theoretical foundation is established for the safety protection of the self-propelled entity target.
