摘要
对测试受高冲击设备圆柱形防护壳体进行了理论和数值分析,并利用ANSYS/LS-DYNA软件模拟了高冲击环境,得到壳体在弹体侵彻过程中的最大应力值,验证分析了中厚型壳体的冲击受力强度、自由面受力强度、拐角受力强度和薄壁型圆柱形壳体的屈曲变形。根据仿真分析结果对测试设备圆柱形防护壳的抗冲击性能进行了评估。
The theoretical and numerical analysis of the cylindrical protective casing of the test equipment was carried out, and the high impact environment was simulated by ANSYS/LS-DYNA software. The maximum stress value of the shell during the penetration process of the projectile was obtained, and it verified on the basis of this. The impact strength of the medium-thickness shell, the strength of the free surface, the strength of the corner and the buckling of the thin-walled cylindrical shell were analyzed. At the same time, the impact resistance of the cylindrical protective casing of the test equipment was evaluated based on the simulation analysis results.
