拖拉机液压悬挂系统故障模型的研究

STUDY ON FAULT MODEL FOR HYDRAULIC MOUNTING SYSTEM OF TRACTOR

以上海-50型拖拉机为例,用故障树分析法(Fault tree analysis),探讨拖拉机液压悬挂系统发生故障的规律,建立了系统故障数学模型,并借助自行研制的检测装置,用逻辑诊断方法进行了验证。为该系统的故障诊断提供了一种方法、设备及相关的理论依据。

Taking Shanghai-50 model tractor as an example, in the means of fault tree analysis, the paper researched fault regular pattern of hydraulic mounting system of tractor, and a mathematical model for fault of the system had been established. In the means of logical diagnosis, the model was verified on the check and measuring equipment developed by myself. It supplied fault diagnosis for hydraulic mounting with a new kind of method, equipment and ve-lative theory.
