摘　　要：热挤压工艺参数对汽车轮毂套管的锻造性能和服役寿命具有重要的影响。首次采用Taguchi理论对EQ153汽车轮毂套管的热挤压工艺进行最优化处理。以不同工艺下的损伤、应变和应力作为目标值,通过灰关联分析和方差分析得到初锻温度、挤压速度和摩擦系数的最佳水平。优化结果良好,对轮毂套管的热挤压具有指导意义。Hot extrusion parameter has great influence on the forging property and service life of the hub tube. The hot extrusion process for EQ153 automotive hub tube has been optimized by use of the Taguchi method for the first time. The damage, stress and strain under different extrusion parameter have been used as the object value. The best level of initial temperature, extrusion speed and friction coefficient have been obtained by grey analysis and variance analysis. The optimization result could guide and control the hot extrusion process of the hub tube.
