分析SDD_8型机车转向架轴箱弹簧发生早期疲劳断裂的现象,指出弹簧断裂的原因是弹簧制造质量和设计余量不足,提出弹簧设计应辅助以有限元方法进行校核,并给出了弹簧改进的方案。
This paper analyzes the phenomenon of early fatigue fracture of axle box spring of SDD_8 locomotive and points out that the cause of spring breakage is the quality of spring manufacturing and the design margin is insufficient. It is suggested that the spring design should be supported by the finite element method to check and the spring improvement Program.
