舰载设备双波冲击试验机中的水锤现象研究

介绍了舰载设备双波冲击试验机正波发生系统的基本结构,对系统中水锤现象进行了分析.建立了正波发生系统的非定常流动模型,采用特征线法对该模型进行求解,分析了系统的动态压力变化情况;建立了系统的恒定流动模型,对两种算法下管路内压力变化情况和冲击锤的速度进行了比较.结果表明系统中存在水锤现象,并可以用非定常流动模型进行描述,该算法下冲击锤速度低于恒定流动模型计算结果.

Water-hammer Phenomena in Naval Dual-wave Shock Test Machine

Shock test machine is used to test the anti-shock ability of the equipment on the ships.Dual-wave shock test machine can simulate the process of underwater explosion and its comparability is better than traditional single-wave shock test machine.To fill the gaps,Naval Academy of Armament and Shanghai Jiao Tong University developed the first dual-wave shock test machine of China.This paper introduces the structure of the positive-wave system of the naval dual-wave shock test machine and analyses the water-ha...
