摘　　要：由于工程机械一般在比较恶劣的环境中工作,因此工程机械会发生各种各样的故障并且很难准确的找到这些故障的发生原因,所以采用基于故障树的模糊推理机制对工程机械进行故障诊断。以提梁机液压卷扬控制系统的"减速机制动器打不开"这一实际故障为例,介绍该方法的应用,从而发现该方法可以极大地减少问题的解决时间,提高解决问题的效率。Generally, the construction machinery is working in a bad environment, so a variety of mechanical failures occur and are difficult to accurately find the cause of these failures. Therefore, fault tree based on fuzzy reasoning mechanism is adopted in fault diagnosis of engineering machinery. This paper introduces the application of this method through the actual fault of the reducer brake not being opened, which found that the method can greatly reduce the time of problem-solving and improve the efficiency of problem-solving.
