航空装备预防性维修工作确定与优化

Study on Determination and Optimization of the Aviation Equipment Preventive Maintenance

现代维修理论制定预防性维修工作的方法是以可靠性为中心的维修分析(RCM A)。为进一步完善预防性维修工作,提出基于使用维修和故障信息基础上的新的分析方法,分析了航空装备维修工程的特点,建立维修--故障作用力模型,结合主成分分析法,得出预防故障的主要维修工作。通过计算预防性维修工作的功能,优先执行功能最大的预防性维修工作。设计了一种新的预防性维修工作优化算法,为合理、适时安排不同的预防性维修工作提供依据。

Traditionally, according to the maintenance theory the preventive maintenance operation is based on the RCMA （Reliability-Centered Maintenance Analysis）.For perfecting the maintenance, it presents a new method based on maintenance and failure information, analyzes the character of aviation equipment maintenance engineering and builds the effect model of maintenance-failure,we gain the main maintenance which inducing the failure. Through computing the function of the preventive maintenance, the biggest is carried out. A new optimization algorithm is designed. The research is of directive significance to planning the reasonable and timely preventive maintenance.
