摘　　要：岸桥的俯仰缠绕系统由左右两侧钢丝绳组成,在俯仰钢丝绳选型计算时,需要考虑一种特殊工况,即一侧钢丝绳断开以后,另外一侧的钢丝绳能够有效负担大梁的重量。本文对这种断绳工况进行了数学建模,分析了这种工况下大梁的受力情况,并对影响冲击系数的因素进行了分析。The winding system in boom pitching gear of the quayside container gantry crane is consisted of steel wire ropes located on its right and left sides. At the verification for the rope＇s strength,a special case needs to be considered that when one side＇s rope is fractured,the other side＇s rope could still have enough capacity to hold on the boom weight. This paper builds up a mathematical model for this special case to analyze the load condition of the boom during this case and the factors that affect the impact coefficients.
