- 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.
