Study on Overall Stiffness of Guide Roller Based on ANSYS

随着现代矿井概念的普及,高速重载提升将是今后立井提升技术的发展重点,滚轮罐耳作为提升系统主要的缓冲元件,其整体刚度特性的研究对立井提升系统的高效、安全运行有重要的意义。首先,通过理论方法分析计算,得出理论刚度;然后,利用ANSYS对滚轮罐耳整体模型仿真分析;最后,通过滚轮罐耳静刚度试验台测量计算并与仿真值相比较。结果表明,随着水平力增大,滚轮罐耳等效刚度先增大后趋于稳定。

With the popularization of modern mine concept,high-speed and heavy-load lifting will be the development direction of shaft lifting technology in the future.Guide rollers are used as the main buffer components of the lifting system.The study of its overall stiffness characteristics is important for the efficient and secure operation of vertical shaft lifting systems.Firstly,the theoretical stiffness is obtained through theoretical analysis and calculation.Then,the overall model of the guide roller is simulated and analyzed using ANSYS.Finally,the measurement of the guide roller static stiffness test rig is compared and compared with the simulation value.The results show that with the increase of the horizontal force,the equivalent stiffness of roller cans first increases and then tends to be stable.
