摘要
绞车是钻机中主要的工作机之一,目前对绞车系统的研究已经基本成熟,但是对其可靠性的研究还不够完善。本文利用故障树分析方法分析建立了JC型绞车故障树,计算出最小割集和结构函数,通过对其结构重要度大小排序,找出其工作中的薄弱环节,为绞车故障分析系统的设计和应用提供参考依据。
Winch is a main working machine of drilling rig.Currently,the research of winch system has been matured,but the study of its reliability is also not perfect.Using the fault tree analysis method, the fault of JC winch system as analyzed and fault tree was drawn.The minimum cut sets and the structure function were obtained and according to the importance of structure function,the relative weak parts of the system were found out.It could be used as reference for the designing and application of the winch system.
