摘　　要：为了准确、高效地识别液压旋挖钻机缓冲平衡阀故障,提出基于T-S模糊故障树的液压旋挖钻机缓冲平衡阀故障诊断方法。分析液压旋挖钻机缓冲平衡阀结构,建立运动学方程,对其旋挖运动特性展开分析。设计T-S模糊门,根据液压旋挖钻机缓冲平衡阀现场的故障数据,结合专家经验,在平衡阀旋挖动力特点的基础上建立T-S模糊故障树,将缓冲阀状态异常作为故障树的顶层事件。利用T-S模型得到故障事件的故障程度,实现液压旋挖钻机缓冲平衡阀的故障诊断。实验结果表明:所提方法诊断效率高、诊断精度高。In order to identify the fault of hydraulic rotary drilling rig buffer balance valve with accuracy and efficiency,a fault diagnosis method of hydraulic rotary drilling rig buffer balance valve based on T-S fuzzy fault tree analysis is proposed.The structure of the buffer balance valve of the hydraulic rotary drilling rig is analyzed,the kinematics equation is established,and the motion characteristics of the rotary drilling rig are analyzed.T-S fuzzy gate is designed.According to the on-site fault data of buffer balance valve of hydraulic rotary drilling rig and expert experience,T-S fuzzy fault tree analysis is established based on the dynamic characteristics of rotary drilling of balance valve,and the abnormal status of buffer valve is regarded as the top event of the fault tree analysis.The T-S model is applied to obtain the fault severity of the fault event and achieve fault diagnosis of the buffer balance valve of the hydraulic rotary drilling rig.The experimental results show that the proposed method has high diagnostic efficiency and accuracy.
