摘　　要：针对舰载超近程反导拦截弹药的侵彻毁伤问题,依据弹塑性动力学和爆炸与冲击动力学理论,建立动能环垂直侵彻导弹靶标的极限穿透速度和剩余速度的动力学模型;依据有限元方法建立了其仿真模型并进行了仿真计算;设计并进行了动能环侵彻5mm厚4340钢板的靶场试验,理论计算、仿真和靶场试验三者相互验证,结果吻合较好,验证了理论模型的正确性。研究结果对于舰载超近程反导拦截弹药的优化设计和冲塞毁伤效应的计算具有重要参考作用。For the penetration and damage problem of the super close-in anti-missile intercepted ammunition,the dynamics models of the kinetic circles′ultimate penetrating speed and the rest speed were founded according to the elastic-plastic dynamics and the explosion and impact dynamics theories.The simulation model was founded and the simulated calculation was executed with the finite element method.The target test of the kinetic circles to penetrate the 5mm 4340#steel span was designed and executed.The results of the theory calculation,simulation and the target test were conformated each other and they were better coincided.The theory model was conformed correctly with the simulated results and the test results.The research results provided a reference for the super close-in anti-missile ammunition′s optimized design and the calculation of the extruded damage influence.
