摘　　要：由于超高压发生器的瞬时压力脉动导致水射流的出口速度不稳定,进而严重影响水射流机床的加工质量。本文以某型水射流切割机床为研究对象,建立其水射流增压系统的数学模型,应用MATLAB中的动态仿真工具软件包SIMU-LINK,对超高压增压系统的压力脉动和高速水射流的出口速度进行仿真研究。通过仿真研究,为改善水射流系统的动态性能提供了依据。The velocity of water jet is unstable due to pressure oscillation of the intensifier, therefore the performance of water jet machining is severely affected. Based on a water jet cutting machine, the mathematical model of the intensifier system for generating high speed water jet was bnilt. The numeric simulation of fluctuation of pressure and velocity of the water jet was made based on the dynamic simulation tool SIMULINK Software package in MATLAB. The dynamic performance of the intensifier system for water jet machine was improved by the simulation result.
