Stress Analysis of High-speed Wheel-rail Contact with Wheel Material Cavity Considered

  • 摘要: 针对高速车辆车轮材料的空洞现象,利用弹塑性有限元方法,建立了车轮材料含有空洞的轮轨接触三维数值模型。模型中采用了非线性的车轮材料本构关系,计算分析了空洞大小、位置和轮重对车轮材料应力应变分布的影响。计算结果表明:轮轨接触作用下,空洞附近车轮材料易出现塑性变形和应力集中现象,且在160°和340°的空洞附近应力和应变值最大;在小于1 mm范围,空洞直径为0.1 mm时车轮材料最易萌生裂纹;当空洞离踏面距离小于15 mm,空洞离踏面距离对车轮疲劳萌生影响明显;随着轮重增加,其空洞附近车轮材料应力应变会随着增大。
