摘　　要：针对复杂钣金产品在设计阶段无法凭经验准确预测成形质量的情况,以摩托车排气管为例,通过四边形网格的划分,设计合理的截面线创建出凹模有限元模型,采取"一步成形法"计算出产品坯料,通过设置如压边力等冲压工艺参数,模拟计算得到产品的成形极限图FLD和厚度分布云图,通过分析为进一步模具设计提供参考。It is very difficult to predict the complex sheet metal forming quality accurately in design stage. Taking the motorcycle exhaust pipe as an example, through the quadrilateral mesh division and the rational design of section lines, fiuite element model of the die is created, one step forming method is used to calculate the product blank. Through setting the pressure side force of stamping process parameters, simulation calculation is carried out to obtain the product of forming limit diagram of FLD and thickness distribution, which provide a reference for the further die design.
