摘要
该文基于对推钢机动力传输系统全面研究,对推钢机液压系统进行了设计,分析了其工作原理,计算了其重要组成部件参数。应用液压组成部件的基本失效概率,通过串联系统可靠度的计算原理建立液压系统可靠性数学模型,并应用MATLAB软件对设计系统进行仿真分析。仿真分析表明:推钢机的可靠性随时间的增长而降低,且其可靠度随时间增长下降速度减缓,仅在限定工作时间段内,才能保证推钢机液压系统的可靠性。
In this paper, the hydraulic system of pusher is designed based on the overall research of pusher power transmission system. Its working principle is analyzed, and the parameters of its important components are calculated. Applying the basic failure probability of hydraulic components, the mathematical model of hydraulic system reliability is established through the calculation principle of series system reliability, and the simulation analysis of the design system is carried out by using MATLAB software. The simulation analysis shows that the reliability of the pusher decreased with time increasing, and the reliability of increasing the rate of decline slowed, only in a limited period of time, in order to ensure the reliability of the hydraulic system of pushing steel machine.
