摘要
针对某汽车左后悬挂架零件拉伸深度大、变形不均匀的特点,利用数值模拟方法和试验比较,制定了多次拉伸成形工艺方案。试验表明:通过数值模拟技术和应变路径相结合的方法可以缩短产品的设计周期,降低生产成本,实现了拉伸工艺参数的优化,为复杂形状拉伸件的工艺制定和优化提供了可靠的保证。
In consideration of the performance of great deep drawing and nonuniform deformation, numerical simulation was utilized to compare with experiment to determine processing plans of multiple drawing for automobile left rear suspension bracket. The findings show that the join of numerical simulation technology and strain paths adjustment can shorten the design cycle and reduce the production costs, realizing the optimization of technological parameters of drawing. This will help to determine and optimize the drawing process of complicated shape parts.
