摘要 为研究钢丝绳罐道提升容器运行时井筒内气体压强变化规律, 求得提升容器侧向气动压力,采用FLUENT软件模拟提升容器在井筒中的运行过程和井筒内空气流场变化过程,得出了井筒内压强具有在X方向近似呈对称分布,在Y方向随着箕斗运行剧烈变化的特点;箕斗相会前受到偏向井壁方向的压力,相会过程中急剧变化,相会后压力恢复到相会之前的水平。研究表明:计算空气流场引起的容器运行时的水平偏移应以稳态空气动力为主。该研究为计算侧向气动压力引起的钢丝绳罐道提升容器的偏移量提供支撑,也为确定钢丝绳罐道提升容器的安全间隙提供了一种新思路。

Abstract: In order to study the distribution of air pressure in the shaft when the hoisted container with rope guide running , and get the lateral aerodynamic force, the process of hoisted container running in the shaft and the variation of air flow field are simulated by the computing software FLUENT. From the study, we can get that the air pressure distribution in X direction is approximately symmetrical, in Y direction changes intensely, and the force is inclined to sidewall before the ships meeting, changes intensely at meeting, and after meeting it returns to the state before meeting. Research shows that the steady aerodynamic force is the main factor to calculate the lateral displacement caused by air flow. The research can support the calculation of lateral displacement caused by air flow, and give a new way to determine the safety clearance in rope-guided shaft.
