摘　　要：通过对提升系统松绳、断绳情况进行理论分析,找出松绳、断绳的具体原因。根据能量守恒定律和胡克定律推算出松绳长度与冲击力的关系式,并结合具体实例,证明新关系式的正确性。最后开发VB界面,使计算过程在实际运用中更方便、快捷。将相关数据带入VB界面,可以计算出常用竖(立)井提升钢丝绳的最大松绳长度,为工程安全设计提供依据。By analyzing the theory of the loose-cable and the rope-broken of the hoisting system, the detail cause of them has found. According to the energy conservation law and Hooke＇s law, determine the loose rope length and the relation between the impact forces, combined with the specific example, prove the correctness of the new relation. Finally, developed a VB interface, made the calculating process in practice more convenient, shortcut. Relevant dates into the VB interface, can calculate maximum rope length of the vertical well, provide basis for engineering safety design.

关 键 词：断绳 冲击力 VB界面 松绳长度
