轨道车辆某型橡胶一系弹簧结构优化

针对轨道车辆某型橡胶一系弹簧，分析初始结构特点及存在的缺陷，提出改善初始结构刚度及疲劳性能的结构优化方案，并利用有限元分析确定了新结构。结果表明，采用流线形型面和圆滑过渡能够很好地解决橡胶型面应力集中问题，极大地减小应变，并有效延长产品疲劳寿命。;The initial structural characteristics and flaws of a primary rubber spring for rail vehicles were analyzed，a structure improvement program to improve stiffness and fatigue properties of initial structure was proposed，and the new structure was obtained by finite element analysis. In the new structure, streamlined profile and smooth transition were applied to reduce the stress concentration on rubber profile. It greatly reduced the strain and effectively extended fatigue life of the product
