水下航行体压力管道水锤及预防措施研究（英文）

Research on the water hammer of underwater vehicle pressure water pipeline and its prevention measures

在水下航行器压力管路快速关阀过程中会产生水锤。本文利用FLOWMASTER软件对管路中的水锤进行仿真,并研究了各种影响因素。同时,研究了预防管路水锤的措施,这对提高水下航行器的隐蔽性和战斗力具有重要的作用。

Water hammer is produced due to the fast shut of electricity-hydraulic ball valve while underwater vehicle pressure water pipeline system suspends working.In this paper,water hammer in the pressure water pipeline is numerically simulated by the Flowmaster software,and various factors affecting the water hammer are studied.Accordingly,methods are developed to prevent the water hammer in the underwater vehicle pressure water pipeline,which is valuable to reduce vibration and noises produced by water hammer in the underwater vehicle pipeline and is practically significant to improve the underwater vehicle stealth and combat capability.
