近年来,热连轧机振动问题显得更加突出和复杂化,众多企业迫切需要解决这一难题。首先对某热连轧机振动现象进行在线监测;然后依据轧机实际参数建立液压弯辊系统和轧机垂直系统的耦合动力学模型,利用MATLAB进行了仿真研究,通过改变液压弯辊系统中控制器参数,获得液压弯辊的控制性能对辊系振动能量的影响,实践表明这是有效抑制振动的措施之一。
In recent years, hot rolling mill vibration problems become more prominent and complex, many companies urgently need to solve this problem. Firstly, the vibration of a hot strip mill was monitored online. Based on the actual parameters of the rolling mill, the coupling dynamics model of the hydraulic bending system and the vertical system of the rolling mill was established and simulated by MATLAB. By changing the controller parameters in the hydraulic bending system, Obtaining the control performance of the hydraulic bending roller has an impact on the vibration energy of the roller system, practice shows that this is one of the measures to effectively suppress the vibration.
