为了提高汽车制动系统的故障诊断能力和效率,在传统的故障树模型的基础上,引入灰色关联分析方法,建立了基于灰色关联度的故障模式分析模型。依据故障树底事件的重要度,计算出各故障模式之间关联度,并按大小进行排列,从而确定导致汽车制动系统失效因素发生的优先顺序。该方法在实践中不仅可以提高诊断工作的效率,也为汽车可靠性设计提供理论依据。

In order to improve the accuracy of automobile brake system fault diagnosis ability, a method of failure analysis based on grey theory was proposed. Gray relational analysis was introduced to failure mode analysis on the basis of the traditional fault tree model to build the new failure analysis model based on grey correlation analysis. Correlation between various failures modes was calculated depend on bottom event importance of the fault tree. The occurrence of factors which lead to the failure of automobile brake system was determined by ranking according to the correlation degree. In practice, the method can not only improve the efficiency of diagnosis, but also provide a theoretical basis for the reliability design of the automobile.
