Abstract
A random process model of structural functional function of components attached to vectoring thrust nozzle was employed, in which strength and stress of components were respectively taken as random variable and stochastic process. By minimizing structural functional function, the problem of dynamic reliability on functional function was converted into static problem. Moreover, according to characteristics of stress random process, minimum variance unbiased estimate of structural reliability of components were employed on the condition that stress process was simplified into Gumber-stationary binomial random process and strength obeyed normal distribution which parameters were unknown.
