摘　　要：在有限元软件ABAQUS中建立连续变截面板的数值模型,以影响变截面板矩形件成形的板料过渡区长度、板料过渡区位置和板料厚度比等为参数,以最大料厚减薄率和板料节约率等为考核目标,通过数值模拟和正交优化方法,对比分析不同方案下最大料厚减薄率和板料节约率,确定最优方案,以提高变截面板的成形性能。结果表明,厚度过渡区的长度对矩形件成形的影响最大,过渡区的位置次之,厚度比的影响最小。Numerical simulation was made on parameters like transition length and position as well as thickness ratio of sheet metals that affect the formation of rectangle box made of tailor rolled blanks. Through numerical simulation and orthogonal optimization,the most thickness reduction ratio and material saving on different conditions were contrasted and analyzed. An optimum scheme was obtained and it could improve the. formability of tailor rolled blank （TRB）. The result indicates that the transition length plays the most important role on thickness reduction ratio and then position, thickness ratio is the least.
