摘要:: 以超高压冷气推进系统为研究背景，针对压力调节模块进行数值模拟研究。通过建立调压模块的流固耦合动力学数学模型，将其工作过程定义为填充、开机和关机三个阶段，得到了不同阶段的调压特性，以及节流孔直径和入口压力对压力调节模块不同阶段的影响规律。仿真结果表明：在不同的工作阶段，节流孔直径和入口压力的增加都使得稳压腔内压力升高，只是达到稳定的时间不同，同时阀芯位移变化也表现出一定的规律性，这都为压力调节模块的设计提供一定参考。

Abstract:: By taking ultrahigh pressure cold gas propulsion system as the research background, numerical stimulation research of the pressure regulating module is carried out in this paper. The properties of pressure regulating, and the influence law of throttle hole diameter and inlet pressure on the pressure regulating module in different stages were achieved by establishing the fluid-solid coupling dynamic mathematical model in pressure regulating module, and defining its working process as three stages (filling, start-up and shutdown). The simulation results show that the increase of throttle hole diameter and inlet pressure can boost the pressure in the pressure stabilizing cavity in different stages, but only the time to reach stable state is different, and the change of valve element displacement also shows certain
