基于蒙特卡罗方法的船用发电柴油机喷油器维护
|
摘要
船舶发电柴油机的关键零部件需要定时进行维护,为了满足必要的可靠度指标,需要获取符合可靠度要求的维修时间点。选择YANMAR 6N21A-V柴油机喷油器,通过对其无故障运行时间的分段,采用蒙特卡罗方法确定不同运行时间段的平均可靠度。结果表明,从56种维修组合中可分别筛选出可靠度为0.7、0.8和0.9的维修方案,为船舶公司或轮机人员制订关键零部件的维修保养时间提供依据。
In observation of the immediate maintenance of key components on a marine diesel engine,it is a necessity to obtain the information about the maintenance schedule required by the reliability index.In this paper,a marine diesel engine YANMAR 6N21A-V was selected,by employing Monte Carlo approach,segmentation on mean time between failure(MTBF) of its injectors was firstly conducted and then used to determine the average reliability within different durations.Results show that the reliability about 0.7,0.8 and 0.9 can respectively be determined based on 56 maintenance schedules.It suggests that the results from the Monte Carlo approach are beneficial to planning the maintenance schedule for marine engineers or ship managers.
