Research on Main Drive System Vibration of Six-Roller Wide Strip Aluminum Cold Rolling Mill

Abstract:

Vibration appears in the main drive system of the six-roller cold rolling mill of one plant. The oscillation frequency is 2.5 Hz. The oscillation cycle is 0.4 second. The oscillation period has nothing to do with the speed. Using the finite element software ANSYS, the low natural frequency is got through the modal analysis and harmonic response analysis based on the measured vibration data from the field. Horizontal vibration is the main vibration mode and it is the electromechanical coupling vibration. Main motor is controlled by IEGT inverter of TEMIC and the low frequency harmonic component is difficult to eliminate. AC drive trap filter is designed to dodge the 2.5 Hz frequency. The solution has achieved the recognition by the TEMIC company. The problem was solved and good results were obtained.
