Analysis and Experiments of Buckling of Precision Products for Automotive Based on the Response-surface Methodology

  • 摘要: 旨在研究复杂曲面类汽车精密制品的翘曲变形情况,在试验设计初期,根据模流分析设计原则,初步确定了影响变形的主要因素的参数值(包括注射时间、模具温度、熔体温度、保压压力曲线和冷却液温度等)。以Z方向的最大变形值作为优化指标,采用CCD(Central Composite Design)二阶响应面设计法,选取熔体温度、保压压力曲线和冷却液温度为试验变量,将响应受多个变量影响的问题进行建模并进行模流分析获得试验结果,采用F检验法检验回归方程的显著性,得出可用的响应面方程,并以此来优化响应,获得最优工艺参数组合,并进行CAE(Computer Aided Engineering)分析检验优化方案的可靠性。对汽车门拉手进行现场跟踪测量,结果表明,与无试验优化的注射成型相比,最优方案可使翘曲变形量减少16%左右,满足精密制品外观功能要求。
