摘要:
气动增压器的动作频率是一个重要的性能参数。当气动增压器结构确定后，频率直接决定推进剂流量等参数。同时，气动增压器的动作频率体现在推进剂出口管路压力的波动上，对出口压力的稳定性有很大影响。研究气动增压器的动作频率，有助于合理选择频率参数，以及气动增压器结构参数和性能参数的匹配。为了研究增压气体性质对气动增压器工作性能的影响，建立了数学模型，利用AMESim软件对气液活塞的工作过程进行了仿真。仿真结果与试验数据对比，一致性较好。
Abstract:
The motion frequency is an important performance parameter of pneumo-pump. When the structure of the pneumo-pump is fixed, its frequency determines the flow rate of propellant and has a great influence on the outlet pressure. Therefore, the research of the operating frequency contributes to selecting a rational frequency parameter and matching the structural parameter and performance parameter of pneumo-pump. In order to explore the influences of gas properties on pneumo-pump performance, a mathematical model was set up and the working process of hydraulic pistons was simulated with AMESim. A comparison between simulation results and test data was made. The comparison results show that they are in good agreement.
