  • Study on vibration characteristics of rolling mill based

    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
