- 摘要:
- 分析了电磁阀的组成和功能，给出了电磁阀的4个典型任务剖面，并由此分析对阀门可靠性产生重要影响的功能结构。用设计参数灵敏度分析法研究了导致阀芯-壳体滑动副卡死的直接原因，认为问题的核心在于多余物导致摩擦力大幅度增加。因此消除滑动副的疲劳磨损和粘着磨损是提高可靠性的关键。用质量功能配置方法找出了与滑动副相关的零件和结构，在灵敏度分析的基础上建立了结构要素的设计思路和原则，研究了螺管式电磁阀的滑动副结构对空间推进系统的适用性，并给出了滑动副结构要素的加工方法和对应的工序质量控制点。
- Abstract:
- Based on the analysis of the function and composition of the solenoid valve, four mission phases of the valve were presented, and the functional structures affecting the reliability significantly were discussed. The method of design sensitivity analysis was presented, and the result shows that the clamping of moving parts was caused by the obvious enhancement of friction with debris. To improve the reliability of sliding pairs, the fatigue and scuffing must be eliminated. On the basis of the design sensitivity analysis, the rules of designing a sliding pairs were established. The applicability of solenoid valve sliding parts' structure for space propulsion system was studied. The manufacturing method and corresponding process quality control point of the sliding parts' structure are offered in this paper.
