摘　　要：为了提升造纸机压光机下辊顶升过程中双缸的同步性,本课题以造纸机压光机钢辊为研究对象,通过分析其顶升作业状态,采用一种作用于压光机下辊的“同等”双缸同步控制方法,基于牛顿第二定律及刚体定轴转动定律建立数学模型,利用Simulink搭建了双缸同步控制系统仿真模型,并进行仿真分析及验证。仿真结果表明,双缸同步控制系统的最大位移同步误差1.7 mm,与原双缸控制方法相比,双缸位移同步误差下降了约88.7%,该方法提高了压光机下辊顶升作业的同步性,可防止线压力不均匀,为造纸机压光机的双缸同步控制提供一定参考。In order to improve the synchronization of the dual cylinders during the lower roller lifting process for the paper machine calender,this study took the steel roller of the paper machine calender as the research object,and analyzed its lifting operation status,adopting an“equivalent”dual cylinder synchronous control method applied to the calender lower roller.Based on the Newton’s second law and the fixed axis rotation law of the rigid body,this study established a mathematical model,built a simulation model of dual cylinder synchronous control system through Simulink,and conducted simulation analysis and verification.The simulation results showed that the maximum displacement synchronization error of the dual cylinder was 1.7 mm,which decreased by about 88.7%compared with the original dual cylinder control method.This method improved the synchronization of the calender lower roller during the lifting operation,and could prevent uneven line pressure and provide reference for the dual cylinder synchronization control of the paper machine calender.
