【Abstract】 With the reliability of multifailure modes of shaft and spring as the practical examples to seek solutions, the paper mainly introduces and analyzes the differences between the O.Ditlevsen theory and the part multifailure modes correlation reliability theory when multifailure modes are related. Their own characteristics are obtained after comparing. Being relative to O.Ditlevsen reliability theory, the computing method of using the part multifailure modes relevant reliability theory is simple so that the calculation precision is raised and the scope of application is expanded.更多还原
