本文利用结构力学的方法,分析了双筒提升机不平衡提升条件下,主轴弯矩的变化规律。得出目前卷简与主轴实际尺寸范围内,主轴弯矩的实际极位仍然发生在钢绳拉力作用于节点(支轮上)位置的时候。在正确选择固绳位置的条件下,对于主轴计算(包括多层缠绕),最多只需计算六个工况。本文还编制了用于主轴设计的程序,它完成主铀的全部计算,并能在诸如疲劳安全系数以及挠度等参数不满足要求时,自动调整主轴尺寸。
In this paper, by using the method of structural mechanics, the variation law of the bending moment of the main shaft under the unbalanced lifting condition of the dual-cylinder hoist is analyzed. The conclusion is drawn that the actual pole position of the spindle bending moment still occurs when the tension of the steel wire acts on the node (the support wheel) within the range of the actual size of the roll and the actual spindle. With the correct selection of the position of the solid rope, a maximum of only six operating conditions are calculated for the spindle calculation (including multi-layer winding). This paper also prepares a program for the spindle design that performs the full calculation of the main uranium and automatically adjusts the spindle size when parameters such as fatigue safety factor and deflection do not meet the requirements.
