Abstract：

Variable cross-section design is generally used on medium-duty and light-duty truck longeron in order to reduce weight. But the stamping deformation of this longeron is uneven, which will lead to warpage and distortion springback defects. The defects will seriously affect assembly quality of truck frame and bring much trouble to daily production. Numerical simulation of truck longeron springback was studied. Springback compensation was designed on longeron mold according to simulation study. Warpage errors are reduced from 15 mm to 2.5 mm and distortion errors are reduced from 5mm to 0.5mm. Experimental results show that stamping accuracy of truck longeron is greatly improved.
