摘　　要：利用ANSYS/FE-SAFE对双梁桥式起重机桥架结构的疲劳情况进行分析,得出其技术与材料属数参数,在Creo Parametric实体建模的基础上,先在ANSYS Workbench中对桥架结构模型进行有限元分析计算,获取等效应力分布数据,结果表明,桥架结构的最大等效应力值小于材料的许用应力,应力疲劳寿命及疲劳寿命安全系数也在设计允许范围内,都能满足强度要求,该桥架结构的设计是可行的。ANSYS/FE-SAFE is used to analyze the fatigue of the bridge structure of double beam bridge crane,and the technical and material property parameters are obtained.On the basis of Creo parametric solid modeling,the finite element analysis and calculation of bridge structure model are carried out in ANSYS Workbench to obtain the equivalent stress distribution data.The results show that the maximum equivalent stress value of the bridge structure is less than the allowable stress of the material,and the stress fatigue life and fatigue life safety factor are within the allowable range of the design,which can meet the strength requirements.The design of the bridge structure is feasible.
