摘　　要：采用特征线法对用导管-气室水力共振系统提高脉冲水射流的强度进行了模拟研究,表明水力共振系统在合适的系统结构参数和流体参数情况下,可以提高导管出口处的压力振幅。气室容积太大会吸收导管起点压力的振幅,使压力脉动减小,太小则不起作用;喷嘴的出口直径越小,越能提高导管出口压力的振幅。A characteristic method is used to research into the hydraulic resonance system of a pipe-air chamber, indicating that with a proper structure parameter and fluid parameter, the system will improve the amplitude of the end-point pressure of the pipe. If the air chamber＇s volume is too large, it will absorb the amplitude of the start-point pressure of the pipe, but if it is too small, it will has no effect. The smaller the diameter of the nozzle is, the more capable it will be when used to improve the amplitude of the end-point pressure.
