Abstract
The vertical vibration often occurs during the rolling production, which has an influence on the accuracy of rolling mill. In order to effectively suppress the vertical vibration of the rolling equipment, the rolling mill model with vibration absorber device was established. Based on the main resonance singularity of the rolling mill system, the best combination of opening parameters was obtained. The best combination of opening parameters helps the rolling mill system work in a stable area. Finally, the effects of different vibration absorber parameters on the vibration characteristics of the rolling mill system were analyzed. Results show that the vibration absorber device can effectively improve the stability of the rolling mill system.
Highlights
With the advancement of technology, high-precision rolling products are becoming more and more significant in intelligent manufacturing
It was found that the vibration energy of the rolling mill system could be transferred to the vibration absorber device
A part of the vibration energy was converted into the heat energy of the vibration absorber device
Summary
With the advancement of technology, high-precision rolling products are becoming more and more significant in intelligent manufacturing. Liu et al set up a nonlinear vertical vibration physical model of the mill equipment, and the vertical vibration characteristics of rolling mill under nonlinear restraint force are studied [10] They analyzed the relationship of mark spacing and vibration source. Sun et al discussed the vertical vibration characteristics of the rolls under different load forces and found the distribution pressure of the rolling products seriously affects the vibration behavior of the rolling mill [11]. The effect of the mass, spring force and friction of the vibration absorber on the vibration behavior of the rolling mill was tested These provided a reliable basis for the vertical vibration of the rolling mill
