摘　　要：舰船供水管道在泄漏处的湍流、空泡溃灭会产生强烈的振动信号,为研究该振动与压力、流速等边界条件的关系,本文根据理论分析建立了振动响应的数学表达式,并通过仿真、实验验证了该表达式的正确性,为进一步研究舰船管道泄漏识别、定位等方向打下基础。Turbulent flow and cavitation collapse of ship water supply pipeline will produce strong vibration signal.To study the relationship between vibration and boundary conditions such as pressure and velocity.In this paper, the mathematical expression of vibration response is established based on theoretical analysis.The correctness of the expression is verified by simulation and experiment.It lays a foundation for further research on identification and location of pipeline leakage.
