Study on vibration characteristics of rolling mill based on vibration absorber

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.

Vibration energy flow of main drive system of hot tandem mill

“…Through path , the power flow delivered to the end of the path is expressed as (4) As shown in Fig. 2, the transmission system of the F2 rolling mill is composed of three sections of simple-uniform supported beams, whose equivalent moments of inertia are I1, I2, and I3, respectively.…”

“…Currently, most of the research work on rolling mill vibration focuses on complex models, such as multi-modal coupling and nonlinear and asymmetric factors [4]. Few studies are based on the coupling effect of energy flow to study the rolling mill vibration.…”
