基于关键零部件技术状态的机械产品定时维修间隔期优化方法

摘要

A study was made of the optimization method of time-based maintenance interval based on the failure pattern in which failure rate function is difficult to acquire in that the reliability functions which characterize the failure pattern are generally unknown. Therefore,the optimization method of time-based maintenance interval based on the key part technical condition was researched in this pa-per. An analysis was made of the idea of optimizing the time-based maintenance interval based on the key part technical condition with the evaluation method of the rationale of the time-based maintenance concept based on the key part technical condition presented. The optimization models of time-based maintenance interval were constructed for inadequate maintenance and excessive maintenance respec-tively.%针对描述产品故障规律的函数很难获得和基于产品故障规律进行定时维修间隔期优化的方法在实际应用中有一定困难的问题，研究了基于产品关键零部件技术状态的定时维修间隔期优化方法。分析了基于关键零部件技术状态信息优化定时维修间隔期的思路，介绍了基于关键零部件技术状态信息评估定时维修方案合理性的方法，分别建立了维修不足和维修过剩时定时维修间隔期的优化模型。
