摘要: 采用ALGOR非线性材料机械运动仿真模块模拟复合材料水雷壳体自由跌落与地面接触、碰撞、受力的全过程;分四种状态进行自由跌落过程模拟分析,研究了碰撞地面和跌落姿态对水雷壳体自由跃落碰撞过程的影响;通过碰撞过程载荷、应力、应变、位移等响应数据的分析对比,得出复合材料水雷壳体抗自由跌落冲击性能的研究结论,为复合材料水雷壳体抗冲击性能评价提供理论支撑。

Abstract: The drop processes of composite torpedo shell including free falling status, contacting with ground status, impacting on ground status and stressing status were simulated by the nonlinear material module of mechanical motion in ALGOR. The effect of ground and drop-posture on the composite torpedo shell during the dropping was investigated by simulating the four statuses respectively. Based on the comparison and analysis of simulation results, including force, stress, strain and displacement, the dropping resistance properties of torpedo composite shell were obtained, which was used to evaluate the impact performance of composite torpedo shell.
