摘要
利用AUTODYN显式有限元程序,计算爆炸冲击波传播过程中三波点的轨迹,将模拟计算结果与试验数据进行了比较;结果表明:AUTODYN有限元程序在模拟爆炸场时,近场的计算结果与试验结果相比,误差相对较大,而中、远场的计算结果与试验的误差相对较小;直接使用AUTODYN模拟爆炸场三波点的轨迹具有一定的工程实用性。
With AUTODYN calculation trajectory of triple point on explosive shock wave propagation process,the simulations calculated results were compared with the test data. The results show that with the AUTODYN simulations calculation results compared with test data,there is large error of near explosion field,while small error of middle and far explosion field. Using AUTODYN calculation trajectory of triple point on explosive field has certain engineering practicability.
