摘　　要：猫道机是一种石油井场输送钻杆到钻台的自动化输送设备,是以液压驱动为主的复杂系统,其中液压故障是导致系统停工的重要原因。以猫道机为例,对复杂液压系统进行了运行可靠性的分析。在分析猫道机结构与工作原理的基础上,建立了相应的可靠性框图,建立了可靠性分析的数学模型。通过对液压元件的可靠性参数和相关性进行分析,计算出猫道机液压系统的可靠度。运用蒙特卡罗法对猫道机液压系统进行随机抽样仿真,从而验证了文中复杂液压系统可靠度计算方法的精确性。The catwalk is one kind of automated conveyor equipment used in the oil well site to convey drill pipes to the drill floor, and also a kind of complex system driven by hydraulic pressure, among which hydraulic failure is an important reason that may lead to system downtime. By using the catwalk as an example, the operational reliability analysis for complex hydraulic system was done. On the basis of evaluating the structure and working principle of the catwalk, the related reliability block diagram and the reliability evaluation of mathematical models were built up. Through the reliability parameters evaluation and correlation analysis of the hydraulic components, figure out the reliability data of catwalk hydraulic system were figured out. By using the Monte Carlo method to random sampling the catwalk hydraulic system, thereby the accuracy of the reliability calculation method in complex hydraulic system is verified.
