With strength-strain model, an improved algorithm for this method, the reliability coefficient of non-linear limit status function is solved by developing Taylor progression, and the distribution parameters of random variables are estimated with experimental sample data. Therefore, the estimation of reliability confidence interval on certain confidence level can be solved when distribution parameters are unknown and limit status function is non-linear.展开更多
文摘Aiming at the limitation of traditional normal distribution structure is put forward.

Therefore, the estimation of reliability confidence interval on certain confidence level can be solved when distribution parameters are unknown and limit status function is non-linear.
