Abstract：

The formability of the laser tailorwelded panoramic sunroof strengthening frame was simulated and optimized by software Autoform, and based on the traditional panoramic sunroof strengthening frame, its formability, cost, production efficiency and so on were compared to provide the theoretical basis for panoramic sunroof strengthening frame produced by laser tailorwelded blanks. Through simulation analysis and process optimization of laser tailorwelded sunroof，the strengthening frame has no formability problems, and the mass of the whole part is reduced by 1.17 kg. Thus, the weight of die is reduced by about 8 t. The panoramic sunroof strengthening frame formed by laser tailorwelded blanks has some advantages in the overall structure of automobile, the technology of refinement,the cost of tooling automobile and the production. At the same time，the body quality of the whole vehicle is improved by the above mentioned structure which provides reference for later body product design and manufacturing process.
