基于六西格玛的转向节轴套热挤压工艺参数模拟优化

Abstract Steering joint sleeve heat extrusion process parameters is the key to the extrusion quality. The paper on the application ofSix Sigma DMAIC improved the process and optimized the hot extrusion process parameters. After the definition and measurement for hotextrusion quality the paper tries to analyze hot extrusion forming process by using the DEFORM software for the simulation. The extrusiontemperature extrusion speed and friction factor of these three parameters are optimized so as to improve the quality of the products andprovide a theoretical basis for the practical production.六西格玛 转向节轴套 DEFORM 优化Key words Six Sigma steering knuckle bush DEFORM optimization中图分类号院TG376 文献标识码院A 文章编号院1006-4311（2014）07-0060-02
