摘要
BHS快速换绳装置的行走机构属于定重载液压系统控制,为了避免由于液压冲击而产生摽绳事故,运用计算流体动力学分析抛物线性渐变节流缓冲油缸的运动特性,得出抛物线性渐变缓冲节流油缸在缓冲3个阶段的特性方程。基于多学科系统建模与仿真平台AMESim对缓冲油缸的运行过程进行仿真研究,模拟出油缸在运行过程中的位移、运动特性曲线,为BHS换绳装置的设计提供了理论依据。
As the BHS head rope swift replacing equipment＇s moving mechanism was belonged to the quantify overloaded hydraulic system control, the computer flow dynamics （CFD） was used to analyze the motion characteristic of parabola gradient throttling cushion cylinder in order to avoid the head rope wrap accident caused by the hydraulic shock, the characteristic equation of the parabo- la gradient throttling cushion cylinder during the cushion＇s three stages was gotten. The cylinder＇s displacement was studied with simula- tion, and the displacement and moving characteristic＇s curve was simulated based on the muhi-disciplinary modeling and simulation platform AMESim. The results provide theoretical foundation for the design of BHS swift head rope replacement equipment.
