摘　　要：铜阳极板圆盘浇铸机在生产中的速度波动严重影响铜阳极板的外形质量,为了提升圆盘运行的平稳性和准确性,对圆盘波动原因进行研究分析。首先要明确各零部件对圆盘运行平稳性的影响,建立包含齿侧隙的双伺服电机传动模型,根据圆盘浇铸机的设计参数,选取齿侧隙等参数作为影响因子,使用基于方差的Sobol方法分析出传动机构中各参数对系统稳定性的影响,得出系统产生振荡的原因。仿真结果表明,减小齿侧隙是提升系统平稳性最有效的方法,每减少0.01°齿侧隙,系统平稳性可提高34.72%。为后续电机控制策略的研究提供了理论依据。The speed fluctuation of the copper anode plate disc casting machine in production seriously affects the appearance quality of the copper anode plate.To improve the stability and accuracy of disc operation,the causes for disc fluctuation are studied and analyzed.Firstly,it is necessary to clarify the influence of each component on the stability of disc operation,a dual servo motor drive model including backlash is established,parameters such as backlash are selected as the influencing factors based on the design parameters of the disc casting machine,and the influence of each parameter of the drive mechanism on the stability of the system is analyzed by using the Sobol method based on the variance to find out the causes for system oscillation.The simulation results show that reducing the backlash is the most effective way to improve the system stability,and the system stability can be improved by 34.72%for every 0.01 reduction in backlash.This provides a theoretical basis for subsequent research of motor control strategies.
