摘　　要：CSP轧机在生产过程中,主传动系统存在强烈的扭转振动和弯曲振动,并且这两种振动相互耦合,呈现出复杂的非线性动力学特性。因此,研究轧机主传动系统的动力学耦合特性,对于抑制轧机振动、保证高效平稳地生产具有重要的理论意义和实用价值。利用已推导的弯扭耦合振动微分方程,对弯曲振动和扭转振动的相互影响因素做了理论分析,并得到了现场实验验证,说明CSP轧机在发生异常振动时确实存在弯扭耦合振动现象。In production process of a CSP mill,its main drive system has strong torsional vibration and lateral vibration.The two vibrations are coupled and show complicated nonlinear dynamic characteristics.Therefore,it is of great importance to study the coupled dynamic characteristics of a mill main drive system for keeping efficient and reposeful production.Using differential equations for lateral and torsional coupled vibration,interactional factors between lateral and torsional vibration were theoretically analyzed and experimentally verified.The results indicated that the phenomenon of lateral and torsional coupled vibration really exits when exceptional vibration of a CSP mill takes place.
