The Vibration Characteristic Research of the Transmission System of the Rolling Mill Based on Absolute Node Coordinates

Abstract:

In order to simulation the vibration characteristics of the transmission system of the rolling mill in Engineering. To determine the cause of the door threshold of rolling mill vibration damage, source the vibration of rolling mill. This article from the perspective of multi body dynamics, Use the rigid flexible coupling dynamic model, fully considered of the time-varying mesh stiffness of the gears, backlash, speed and other factors. Simulation the vibration characteristics of the transmission system of the rolling mill in different tooth side clearance and different speed. The result show that, with the increasing of the backlash, the vibration amplitude of the output shaft increase first and then decrease and then increase. Motion state by no impact to unilateral shock, bilateral impact and then enters to a chaotic state finally to no impact. Through dynamics simulation, can draw the vibration characteristics in different tooth side clearance and different speed of the transmission system of the rolling mill, the theory basis for the fault diagnosis of the transmission system of the rolling mill.
