摘　　要：针对DC03车用冷轧钢板,以矩形件和轿车座椅盆型底座简化件为研究对象,采用数值模拟的方法,系统研究了不同压边条件对座盆拉伸成形的影响,得到该件最优压边力控制方式,使拉伸件不出现起皱和拉破现象,同时零件减薄率最小。For the DC03cold-rolled steel blank in car manufacture, we take the simplified models from the rectangular and basin seat pieces as the objects to study the influences of different forces on the basin modeling with the numerical simulation method. The optimal force control strategy is obtained to ensure that no wrinklings and breakings appear at different tensile forces while the thinning rate is
