摘　　要：介绍了线路捣固车基本参数以及主车架的结构特点,利用ANSYS软件建立车架结构的有限元分析模型,基于欧洲EN12663标准对车架结构进行刚度、静强度、疲劳强度和模态分析。计算结果表明:车架垂向最大变形为11.135mm,最大应力为297.74 MPa,小于材料屈服极限,满足车架刚度和静强度要求。采用Goodman疲劳曲线图对车架疲劳强度进行评估,车架各部位节点的最小安全系数均大于1,说明车架疲劳强度满足标准要求。This paper introduced basic parameters of tamping vehicle and the frame structure characteristics.In addition,finite element analysis model of the frame structure was established by using ANSYS software,in which the stiffness,static strength,fatigue strength and mode were analyzed based on the Europe standard EN12663.The calculated result shows that the maximum vertical deformation of the frame is 11.135 mm and the maximum stress is 297.74 MPa,which is less than the yield limitation of material and satisfies the requirement of frame stiffness and static strength.Evaluating the frame fatigue strength via Goodman fatigue curve,the minimum safety coefficients of each node in the frame are less than 1.00,which is of agreement with the requirement of Europe standard.
