Abstract

To conduct quantitative analysis on the dynamic characteristics of cryogenic pneumatic valve to satisfy reliability demand, the time characteristics of cryogenic pneumatic valve were analyzed by means of the operation principle of cryogenic pneumatic valve, and dynamic characteristics model of cryogenic pneumatic valve was established by velocity dynamics theory. Based on this analysis, the key influencing factor can be defined and nonlinear quantitative analysis between dynamic characteristics and influencing factors can be completed of cryogenic pneumatic valve by principal component analysis (PCA). Finally, effectiveness of the proposed method was verified by a case study. It has shown the proposed method can improve response time and reliability of cryogenic pneumatic valve, and can provide a support for performance evaluation to rocket engine.
