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.
