摘　　要：针对船舶操舵控制系统的可靠性分析问题,以一种船舶操舵控制系统为例进行可靠性分析,分别建立了该型船舶操舵控制系统的基本可靠性及任务可靠性数学模型,使用元器件应力分析法计算该型船舶操舵控制系统内所有元器件的失效率,得出两种模型的可靠度及平均故障间隔时间指标值,对比计算结果表明,该系统的任务可靠性远高于基本可靠性,这种可靠性分析方法也为同类控制系统的可靠性分析提供了新思路。According to the reliability analysis of ship steering control system,the reliability analysis of a ship steering control system is taken as an example to establish the basic reliability and task reliability mathematical model of the ship steering control system respectively.The method is used to calculate the failure rate of all the components in the ship steering control system.The re-liability and the mean time between failures of the two models are obtained.The comparison results show that the reliability of the system is much higher than the basic reliability,This reliability analysis method also provides a new idea for the reliability analysis of similar control systems.
