摘要
对某型舰船管路系统在水下爆炸作用下的冲击响应进行了仿真及试验分析,得出如下结论:加速度响应最大值的仿真值与试验值的误差在30%以内;应变响应仿真的绝对值最大值与试验值最大值的误差在30%以内;随着爆炸距离的增大,最大冲击位移呈递减趋势;最大冲击应力也呈递减趋势,但出现的位置一般为弯管处.仿真及试验的结果表明应用ANSYS软件对舰船管路系统在水下爆炸作用下的冲击响应进行计算是可行的.
Shock response underwater explosive of piping system on ship is analyzed by simulation and experiment.This conclusion can be gained：The maximum of acceleration response between simulation and experiment is within 30%;The maximum of strain response between simulation and experiment is within 30%too;With the distance between the mine and ship expanding,the maximum of shock displacement decreases;With the distance between the mine and ship expanding,the maximum of shock stress also decreases.But the position of the shock stress is commonly at the bend.The result between simulation and experiment proves that the shock response underwater explosive of piping system on ship can be computed by ANSYS code and the method gives a base of the structural anti-shock optimization design of piping system on ship.
