摘　　要：基于HyperMesh软件建立出构架的有限元模型,依据UIC 515-4和EN 13749标准计算构架在正常和超常运营两种工况下的载荷,利用ANSYS软件对模型进行分析,计算结果显示构架不能满足静强度和疲劳强度的标准要求。基于此,提出了新的构架结构设计方案,对新的结构方案进行有限元分析。最终研究结果显示:优化后的构架满足静强度标准要求,且所有焊缝的疲劳强度均在Goodman-smith疲劳极限图内,说明疲劳满足标准要求。该分析结果为窄轨客车转向架构架优化设计提供了理论基础与指导。The finite element model of the frame was built based on HyperMesh software.The load of the frame under normal and abnormal operating conditions were calculated and loaded according to UIC 515-4 and EN-13749 standards.The model was analyzed by ANSYS software.The calculation results showed that the frame⁃work was not meet the standard requirements for static strength and fatigue strength.Based on this,an improved scheme of the framework structure design was proposed and the new structural scheme was analyzed by finite ele⁃ment analysis.The final research results showed that the optimized meets the static strength standard require⁃ments,and the fatigue strengths of all welds are within the Goodman-smith fatigue limit diagram,indicating that the fatigue meets the standard requirements.The analysis results provide theoretical basis and guidance for the optimal design of the narrow-rail passenger car steering frame.
