摘要
Abstract
The hydraulic system has the advantages of smooth operation,convenient operation and control,and high power density.It is widely used in large and medium-sized helicopters to provide driving force for their control systems.Its reliable operation is crucial to ensuring helicopter control capabilities.Residual design is usually used to ensure the hydraulic system's mission reliability.This paper takes the redundant hydraulic system as the research object,considers the characteristics of system components that are failure-related and complex and changeable failure laws,uses a proportional risk model to characterize the impact of load on component failure rate,and establishes a reliability model of a common cause failure system based on Bayesian networks;on this basis,the static Bayesian network is expanded to a dynamic Bayesian network model including time factors to evaluate the reliability of the system.关键词
