摘　　要：为了研究水下武器高速水喷流噪声问题,设计了高速水喷流实验装置,并运用相关理论建立了整个装置实验过程的数学模型,并进行了数字仿真,求取了实验过程中气瓶和气水缸的压力以及水喷流速度的变化规律。仿真结果表明,该方案可在一定时间内保持喷口高速水流速度的稳定性,可以满足实验要求,为下一步的实验研究提供参考。To investigate the water jet noise of high-speed underwater weapon, we design a high-speed water jet device for experiment, and establish four models, including gas state model of supplemental cylinder, gas flow model of connecting pipe, gas state model of pneumatic-hydraulic cylinder, and hydrodynamic model of nozzle. We obtain the change rules of pressure from gas cylinder and pneumatic-hydraulic cylinder and water jet speed by numerical simulation. The results show that the device ean keep stable high-speed water jet at nozzle within a certain period, and satisfy the demand of the experiment.
