装甲车辆发动机环境影响因素指标分析

为综合评估环境因素对装甲车辆发动机技术状态及使用寿命的影响,分析了装甲车辆发动机环境影响因素,构建了环境影响因素指标体系,选取相关性分析方法对指标体系进行优化约简,应用层次分析法对约简后的指标权重进行定量计算,得出空气含尘量因素对发动机的使用影响最大,其次为空气温度、大气压力和负荷变化、维护保养因素影响最小的结论。

Analysis of Environmental InfluenceFactor Indexes on Armored Vehicle Engine

The influencing factors of environment on armored vehicle engine technical state and service life were analyzed.The influencing factors index system was established,which was optimized and reduced by using the relativity analysis method chosen.The weight values of the indexes were calculated quantificationally by AHP.It was concluded that the dust quantity has the most significant influence on the engine;the next significant factors are air temperature,air pressure,and loading;the maintenance factor is the least significant.
