摘　　要：注塑模浇注系统设计是模具设计中较为重要的一环,因此对浇注系统的优化设计研究开展得较早,但在已有的研究中,均没有考虑随机因素波动对成型质量的影响。针对该问题,选取最大翘曲变形量为成型质量指标,提出了基于可拓关联变量筛选、移动最小二乘及蚁群优化的浇注系统稳健设计方法,通过数值模拟及实例验证,表明该方法减小了响应的方差,并有效地提高了塑件的尺寸公差。As the design of runner system in injection mold is very important for mold design,the study on optimum design of runner system is developed early. It wasn′t considered that random factors influence the molding quality in existing study. Aiming at this problem,the maximum warpage quantity was selected as a measurement of molding quality,and the method of robust design was provided based on variable filter using extension relation,moving least square and ant colony algorithm. It shows that the response variance is decreased and the dimension tolerance of plastic product is improved by this method,according to computer aided engineering （CAE） and experiment.
