The three-dimensional model and finite element model of alu-minum alloy axle-box is established by CERO and ANSYS,respectively. Based on the EN 13749-2005 standard,the stress state and fatigue strength of aluminum alloy axle-box under the super load and operation conditions are analyzed by ANSYS Workbench. Through static strength and fatigue strength analysis,the safety and reliability of aluminum alloy axle-box structure are verified. 轴箱体 铝合金 静强度 疲劳强度 Workbench axle-box aluminum alloy static strength fatigue strength Workbench U270.3 国家重点研发计划资助(2016YFB1200501) 2022-03-08 1 50
