摘要
结合AUTODYN三维非线性有限元分析软件的使用经验,通过算例研究External Gap、Trajectory两种Lagrange/Lagrange接触算法对穿甲问题仿真计算效率及结果可靠性的影响。通过仿真计算结果与试验结果的比较,给出了穿甲过程仿真计算中适宜采用的求解器和接触算法组合。
Based on the experience, the effects of interaction algorithm of External Gap and Trajectory on the simulation results and the solution efficiency of the penetrating process were studied by combining with simulation examples using the AUTODYN nonlinear software. The optimized combination of the solver type and the interaction algorithm which is suitable for simulating the armor-piercing problems was given by comparing the simulation result with the experimental result.
