摘　　要：导管-气室系统可以引发水力共振,提高脉冲射流的强度.影响水力共振的因素很多,针对一特定的水力共振系统,就导管长度、导管内径、喷嘴出口内径、调制频率、气室初始容积等因素对水力共振的影响逐一进行了计算机模拟分析,得到了各因素对导管终点压力振幅的影响趋势图,为开展实验研究提供了有力的理论指导.The system that is composed of pipe and air chamber is able to induce resonance, which will prompt the efficiency of pulsed jet. Many factors that influence hydraulic resonance such as length of pipe, inner diameter of pipe, inner diameter of outlet nozzle, modulate frequency and preliminary volume of air chamber etc. Use computer to simulate and analyze how these factors influence hydraulic resonance. Acquire the influence trend figures of these factors on amplitude of end - point pressure of pipe, and these figures will provide the guidance for experimentation.
