Abstract
Jet pipe servo valve is a key hydraulic control component in aerospace. Work environment usually brings random vibration to jet pipe servo valve affecting its reliability. In order to explore conditions for high reliability, a dynamic model is developed to describe the performance indexes of jet pipe servo valve under random vibration environment. Null shift is the main performance index to evaluate the performance of jet pipe servo valve under random vibration environment. Because of the implicit expression of null shift, response surface method (RSM) is introduced to develop the null shift in a quadratic polynomial with no cross term type of design parameters. Monte Carlo method is proposed to calculate the reliability considering the mean and standard deviation of parameters. Dimensionless mean and standard-deviation reliability sensitivities are researched and importance ranking shows the most key parameters. Reliability and reliability sensitivity varied with most key parameters are extended and reasonable parameters are recommended on the premise of high reliability and low reliability sensitivity.
