基于相似系统理论的装甲车辆发动机使用状态评价研究

目的综合预测装甲车辆发动机使用寿命。方法通过相关性分析构建发动机使用环境因素指标体系，应用层次分析法进行指标权重确定。将发动机不同使用环境作为相似系统，应用相似系统理论及度量方法，定量评价装甲车辆发动机使用环境系统，通过定义发动机使用条件修正系数，计算发动机在不同使用环境下的实际摩托小时消耗。结果得到发动机使用环境因素指标权重集为0．074，0．074，0．11，0．074，0．074，0．044，0．22，0．11，0．22]。结论相似系统理论及度量方法能够应用于装甲车辆发动机使用环境系统的定量评估。

Evaluation Study on the Service Status of Armored Vehicle Engine Based on the Similarity System Theory

Objective To forecast the service life of the armored vehicle engine comprehensively.Methods The influence factor index system of the armored vehicle engine servicing was established by means of the relativity analysis method, while the weights of the indexes were calculated by AHP. Taken as similar systems, different engine using environments were quantitatively evaluated by the application of the similarity system theory and its measurement Methods , and the actual consumption of motor hours for the engine under different using conditions were figured out by defining the engine service status correctional coefficient.Resultsthe weight matrix of the engine using influence factor indexes was found to be 0.074, 0.074, 0.11, 0.074, 0.074, 0.044, 0.22, 0.11, 0.22]. Conclusion The similarity system theory and its measurement Methods could be applied in the evaluation of the service status of armored vehicle engine.
