JUMPING AND VIBRATION ANALYSIS OF STRING OF HOISTING WIRE ROPE

摘要: 文章考虑轴向运动分析了提升绳弦段的横向非线性振动特征，讨论了跳绳事故发生的几何条件，结论指出，弦的横振动振型畸变是引发跳绳事故的主要原因

Abstract: In this paper, considering the spool velocity we analysed the nonlinear vibration characteristics of string of hoisting wire rope and discussed the condition of rope jumping. It was found that the main reason causing accident of rope jumping is abnormal change of the vibration mode.
