摘　　要：在对推钢机传动系统相关资料深入研究的基础上,设计了一套液压传动系统,详细阐述其工作原理,并对其重要元件的参数进行计算。基于液压元件基本失效概率,应用串联系统的可靠度计算方法建立该液压系统的可靠性数学模型,最后利用MATLAB软件进行了仿真分析。结果表明:工作时间越长,推钢机液压系统的可靠性越低,而且其可靠度随着时间先下降较快,后下降较缓,只有限定工作时间,液压系统的可靠性才能得到保障。The hydraulic system of a pusher drive system was designed based on the analysis of the related materials, and its work principle was introduced, and the parameters of important components in the hydraulic system were calculated.Based on the basic fail-ure probability of the hydraulic element, the reliability mathematical model of the hydraulic system was established by using the relia-bility calculation method of the series system, and the simulation analysis was carried out by using the MATLAB software. The simula-tion results show that increasing working hours can short reliability of pusher hydraulic system, and its reliability decrease rapidly first along with the time, then decrease slowly gradually, the reliability can be guaranteed in the limited working time.
