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。本文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。
Actually on the manufacturing of CSP mill, main drive system will produce strong torsional vibration and lateral vibration. The two vibrations are coupled and take on complicated nonlinear dynamic characteristics. Therefore it is of great theoretic and applied importance to carry through researches on dynamic coupling characteristics of mill main drive system to make sure efficient and reposeful production of the mill. Using differential equations for coupling of lateral and torsional vibration which were predefined, interactional factors between lateral and torsional vibration are theoretically analyzed and experimentally proved. This indicates that coupling phenomenon of lateral and torsional vibration really exits while exceptional vibration of CSP mill is taking place.
