摘要
基于有限元疲劳分析方法提取弹簧盘力学模型,建立了弹簧盘的有限元模型。针对某种型号轿车的悬架采用Workbench软件对弹簧盘进行应力计算,并对其进行了疲劳寿命预测。利用S-N曲线和Goodman修正理论分析随机载荷状况下弹簧盘的疲劳寿命,并对弹簧盘薄弱部位进行了结构优化设计。
By finite element method, the finite element model bench software was used to calculate the stress of the spring curve and Goodman revision theory, the fatigue life of the structure of the spring plate was optimized. of the spring-seat of an automobile absorber was set up. The Work- plate, and the fatigue life of the spring plate was predicted. By S--N spring plate under random loading conditions was analyzed, and the
