The Research on Friction Impacting on Drawing High-Strength Steel
The paper’s main content is that simulating the process—drawing the high-strength steel-DP500 which is used on automobile to the cylindrical cup through the commercial finite element simulation software—Dynaform. Through the simulation, the author analyzes the effect that friction impacts on drawing high-strength steel. The result is that: if the friction coefficient between the blank and the die declines, it can significantly improve the uniform of the blank’s thickness distribution; it can enlarge the processing range of DP500 steel through decreasing the friction coefficient; the springback is sensitive to the change of the friction condition. Generally speaking, in drawing process, improving the friction coefficient is very important to increase the drawing performance of the cylindrical parts.
