摘　　要：以36t集装箱门式起重机为例,对不同轨道固定方式下钢轨对起重机金属结构的影响进行理论分析,并利用有限元软件建立不同情况下钢轨与起重机门架的相互关系,对模型进行加载求解。通过对结果的比较,说明了采用焊接式轨道固定方式可以较好地改善结构刚度、降低主梁应力,有利于减轻起重机结构自重。Taking 36 t container gantry crane as an example,the paper performs the theoretical analysis for the effect of the steel rail of different track mounting method on the metal structure of gantry crane,and utilizes the finite element software to establish the interrelations between steel and crane gantry under different conditions,and to load and solve the model.The comparison of the results shows that the track adopting the welding mounting method can greatly improve the structure rigidity,decrease the stress of the main girder,and reduce the self-weight of the crane effectively.
