备注

电磁阀在航天器中应用广泛。消反峰电路是电磁阀控制系统中重要的组成部分,且对电磁阀的性能有显著影响。为了获得消反峰电路对电磁阀性能的影响,基于Maxwell软件对某轴流直动式电磁阀及其消反峰电路进行研究。通过将电磁阀某工况下的静态和瞬态仿真结果与试验数据进行对比,验证了仿真模型的有效性。同时仿真对比了有、无消反峰电路及不同消峰电阻下的电磁阀性能,得到释放响应时间随消峰电阻的增大而减小,而感应电动势随消峰电阻的增大而增大的规律,同时发现消峰电阻对电磁阀性能的影响存在一个转折点,选择此点作为电磁阀控制系统的设计点可以得到更优的方案,进而提出从消反峰电路角度优化电磁阀控制系统的方案,为电磁阀控制系统的优化设计提供参考。
The solenoid valves are widely used in spacecraft. The anti-peak circuit is the important component of control system within solenoid valves and has significant influences on performance of solenoid valves. In order to obtain the influence of anti-peak circuit on the performance of solenoid valves, a kind of axial direct acting solenoid valve and anti-peak circuit were studied based on simulation with Maxwell software. The reliability of simulation modeling was verified by comparison of experiment data and simulation results on static and transient conditions. Meanwhile, by simulating the solenoid valves at different anti-peak resistances with or without anti-peak circuit, the performance of solenoid valves was obtained. The release response time decreases with the increase of anti-peak resistance, while the induced voltage increases with the increase of anti-peak resistance. At the same time, it was found that there is a turning point of anti-peak resistance on the performance of the solenoid valve. A better plan can be obtained on this turning point. Furthermore, an optimized plan of solenoid valves was proposed from the viewpoint of anti-peak circuit, which provides reference for the design of solenoid valves system.
