## Analysis and Modeling about Torsion Vibration for Main Drive System of Mill

Wang Qin (CISDI Engineering Co.,Ltd.,Chongqing400013)
By using the Lagrange equation,a general mathematical model function for drive system torsion and vibration analysis was built,and the system inherent motion was analyzed.Based on kinetic theory,the system′s dynamic responses under different loading molds were studied,the torque′s amplifying multiplier of torsion vibration was figured out,and the sensitivity of the system was analyzed.Base on these results,taking a drive system of a mill for example,the key parameters of the torsion vibration characteristics was analyzed,then compare and analysis them with the test results.The results showed that it is effective for the method to analyze torsion vibration characteristics of the system.
