Abstract

The dynamic characteristics of mechanical drive system have a direct impact on the safety of the equipment and quality of products. A general solution model for the dynamic response system of straight string torsional vibration system was derived to solve the problem that the structure size of transmission parts is adjusted by experience, when the mechanical torque amplification of mechanical drive system is too large. Based on a rolling mill the raw data, the analytical results were used to compare with the block diagram of Matlab / Simulink. The compared results show that they are consistent completely. On the basis of the proposed model, the structure parameters optimization of the rolling mill was applied to solve the problem of the large torque amplification factor of the steel plant. The optimization results show that the maximum torque multiple can be greatly reduced by changing the stiffness of a component, and the safety of the transmission system can be also improved.

Key words
