2) free transverse vibration of rolls
辊系横向自由振动
1.
According to Euler-Bernoulli beam theory, the coupled equations of free transverse vibration of rolls were solved based on modal superposition method.
研究结果表明:四辊轧机辊系横向振动包括2个无限序列的自然频率ω1n和ω2n;辊系横向自由振动由2种振动模式组成,即低频的同步振动和高频的异步振动;辊系横向振动中模式n=1起主要作用,低阶时工作辊的振动比支承辊的振动剧烈;高阶时支承辊振幅大于工作辊振幅,奇数阶振幅大于偶数阶振幅;轧辊横向振动对带材板形质量有重要影响。
