考虑分布和传递模型的机械系统可靠性分配方法
A Reliability Allocation Method Considering Distribution and Transmission Models for Mechanical Systems
摘要
Abstract
To address the problems of the allocation reliability of lower-level units being greater than that of the upper-level unit in the multi-layer structure reliability allocation of mechanical sys-tems,a novel reliability allocation method was proposed.Firstly,the mechanical systems were divid-ed into a system-function-motion-action(SFMA)hierarchy structure.Then,according to the hierarchy structure consisting of distribution and transmission models,the reliability allocation techniques were proposed by combining the minimum cost method and reliability function,and the reliability allocation models of the mechanical systems,function units,motion units,and sub-motion units were estab-lished from top to bottom.Finally,taking the gear grinding machine as an example,the feasibility and effectiveness of the proposed method were verified.关键词
