某型自行火炮传动系统延迟时间维修建模实例研究

A Case Study on Delay-time Maintenance Modeling for Self-propelled Gun＇s Drive System

对某型自行火炮底盘传动系统维修保障现状和维修数据进行分析,引入延迟时间概念及其维修建模方法,建立延迟时间维修优化模型,提出主客观数据相结合的贝叶斯参数估计方法。考虑到设备的客观数据不足的情况,首先利用主观数据进行参数估计,在此基础上,再通过逐步完善的客观数据进行参数修正。最后,在一些满足实际情况的假定条件下,运用建立的延迟时间费用模型对检测周期进行了优化分析。

First, Analyzing practical maintenance status and information of self-propelled gun＇ s drive system is analyzed. Then, the concept of delay time and its maintenance theory are introduced. In delay time maintenance model Bayesian parameter estimation method is used. When objective information is lacking, consider using subjective data, and then modify parameter with increased objective maintenance data. Finally delay time model is established to obtain optimum inspection cycle in some practical conditions.
