基于故障树模型的全回转舵桨液压系统可靠性分析

Reliability analysis of hydraulic system of full rotary rudder pitch based on fault tree model

文章针对全回转舵桨液压系统可靠性进行了研究,首先对舵桨液压系统工作原理进行了分析,建立舵桨液压系统的可靠性框图及故障树模型,并结合拖轮的实际运行情况,对舵桨液压系统的可靠度进行评估,最后对提高舵桨液压系统可靠性提出了一些建议。

In this paper,the reliability of the hydraulic system of the full-rotation rudder propeller is studied.Firstly,the working principle of the rudder propeller hydraulic system is analyzed. The reliability block diagram and fault tree model of the rudder propeller hydraulic system are established,and the actual operation of the tugboat is combined with the rudder. The reliability of the paddle hydraulic system was evaluated,and finally some suggestions were made to improve the reliability of the rudder hydraulic system.
