| 摘 要： | 在燃气流量调节系统实验过程中,为了控制燃气发生器的压强,分析锥形阀几何外形对喉部面积的影响.建立不同锥角和锥阀半径的锥阀数学模型,进行Matlab仿真,分析锥体半角和喷管直径对调节系统的影响.由仿真结果可知:在设计锥形阀的几何外形和喷管直径时,需要考虑调节阀行程、喉部面积、电机控制精度和加工精度等因素.该研究可为固体火箭冲压发动机燃气发生器的控制提供一定的参考.

| Abstract: | For controlling gas generator pressure, analyze the influence of geometry shape of need-type valve on laryngeal acreage in gas regulation system test. Establish need-type valve math models with different cone angle and radium. Carry out Matlab simulation, and analyze influence of cone semi-angle and nozzle diameter on regulation system. The simulation results show that we should consider valve stroke, laryngeal acreage, motor control precision and machining precision when design geometry shape and nozzle diameter of need-type valve. The research gives reference for solid rocket ramjet gas generator control. |
