| 摘 要： | 针对宝钢2030mm冷连轧机第四架的颤振现象,将实际轧机的垂直振动简化为六自由度不对称质量—弹簧系统,通过机械系统动力学分析软件ADAMS建立了该轧机垂直振动的虚拟样机模型,并利用ADAMS/Vibration求解了系统各阶固有频率和模态主振型,求解结果与实测结果相符。确定该颤振为第三倍频程颤振,并通过模拟振源的仿真实验,证明增大液压压下系统的阻尼可以有效地抑制这种颤振。 |

| Abstract: | The vertical vibration of mill stand was simplified to 6 degrees of freedom(DOF)spring-mass dissymmetric system according to the chatter phenomenon of stand 4 of Baosteel's 2030mm Tandem cold mill(TCM).A virtual prototyping model based on the simplified model of the chatter was built by using mechanical dynamics analysis software 'ADAMS'.In this study,undamped natural frequency and mode shapes may be calculated with the help of 'ADAMS/Vibration' which is a module of 'ADAMS'.The results,which is in accord with ones of field-test,prove that this kind of chatter is the third-octave-mode one by analysis.An chatter experiment by simulating its vibration actuator was designed to analyze the damp's effect on the chatter.When the damp of hydraulic screw-down system is increased,the third-octave-mode chatter will be effectively restrained. |
