An upper beam is investigated by combination of finite element simulation and tryout methods. The results of deformation simulation and grid experiment were studied. The results show that the direction of principal and side strain in the crack area simulated by CAE software are same as the results received by grid experiment. The result gives a direction for solving the crack problems. It is important that the blank size in both ends is reduced to decrease the bending stress in the die radius. But the effect is very limited for the end region is far from crack area. Combined with the method of reducing the blank size, decreasing the height of the drawbead, enlarging the die radius, improving the smoothness the tension stress is decreased effectively. And the qualified drawing panel is produced finally.
