摘　　要：为确定门座式起重机的起升机构钢丝绳卷筒部分在不同工况和缠绕方式下的结构强度,首先建立了门座式起重机多体动力学模型,分析门座式起重机不同工况下的动态载荷,根据各工况卷筒的动态受力,确定卷筒最大载荷;其次建立卷筒有限元模型,分析了钢丝绳缠绕圈数、初始缠绕位置对卷筒应力分布的影响;最后找到了最危险的钢丝绳缠绕方式,分析了卷筒的最大应力情况并校核,结果表明卷筒结构达到强度要求。通过对起重机卷筒结构强度设计分析,对门座起重机的设计和使用具有应用价值。To determine the structural strength of the steel wire rope drum in the lifting mechanism of the gantry crane under various working conditions and winding methods,a multi-body dynamic model of the gantry crane is established.The dynamic load of the gantry crane under different working conditions is analyzed.Based on the dynamic force acting on the drum under different working conditions,the maximum load of the drum is determined.Then a finite element model of the drum is built to analyze the influence of the number of wire rope windings and the initial winding position on the stress distribution of the drum.Finally,the most critical wire rope winding mode is identified,and the maximum stress of the drum is analyzed and evaluated.The results indicate that the drum structure meets the strength requirements.This study has offered valuable insights for the design and operation of gantry cranes.
