Abstract
Based on the hydraulic calculation of AMEsim software, adjust the pipeline and working conditions of the trim balance system, and explore the influence of water transfer pressure, pipeline length and valve closing time on the transient pressure fluctuation during the working process, and obtain the pressure change law and corresponding Relationship, according to the analysis gives preliminary optimization suggestions, sums up the scheme and scope of reducing water transfer pressure, shortening pipeline length, extending valve closing time, providing reference for optimizing system design and control, and proposing control from noise source level The method of transient noise caused by water hammer phenomenon provides an idea for controlling the transient noise of pressurized pipelines of ships and underwater vehicles.
