摘　　要：牵伸罗拉的周期性振动分为轴向振动和径向振动(扭振),两者对布面的影响不同,尤以径向振动对布面影响显著且危害很大,易形成大面积的疵布,影响企业的经济效益,但是通过各种实验检验、分析可以提前预防或减少损失。Periodical vibration of draft roller can be classified as axial and radial vibrations which affect the product quality differently. Its radial vibration causes large area defects on the product. Inspections and analyses of the vibration can prevent or reduce product defects.
