【Abstract】 Equations of calculating reliability of 5 types different kinds of stress and strength com-binations were derived, based on interference theory of stress and strength of reliability calculation,and the high precision solutions of reliability were given by numerical integral. The visualized opera-tion platform was established for reliability design, which makes it easy to carry out reliability design.This research has made the accurate reliability design having a leap development.更多还原
