摘要
目前,复杂设备的维修维护往往是基于多部件的,然而单个部件往往具有多故障模式,且故障之间具有复杂的关联关系,导致基于多部件的维修决策方案并不一定合理。针对这一难题,提出一种复杂机械装备预防性维修决策方法,与传统的基于多部件的预防性维修决策不同,从故障模式的角度切入分析。根据系统结构和功能特征进行关键故障模式辨识,并将其分为突发类和退化类两类。讨论了复杂机械设备故障模式之间的依赖性、维修级别和维修效果等,进一步利用故障时间分布即寿命分布构建预防性维修决策的目标成本函数,并通过遗传算法实现含整型约束的非线性优化问题求解。所提出的方法在某镗床滑枕进给传统子系统中得到验证,并表现出良好性能。
Based on the analysis of multiple failure modes,a Preventive Maintenance(PM)scheduling for complex mechanical device was proposed.According to system structure and function features,the key failure modes were identified.The dependences between failure modes,the maintenance level and the maintenance effects of complex mechanical device were discussed.The objective cost function of PM was constructed further by using failure time distribution,and the integer-constrained nonlinear optimization problem achieved by genetic algorithm was adopted to solve this function.The proposed approach was illustrated in a ram feed subsystem of a boring machine,and theeffectiveness was proved.
