摘　　要：对比分析了连续变截面辊轧板(TRB)和激光拼焊板(TWB)的成形过程,综合评价两类典型变截面板的拉伸、冲压成形特性、热成形性能及其当前实际应用得出:相比等厚板,TRB和TWB均能明显提高板材承载性,减轻板材重量,在汽车轻量化方面应用非常广泛.TWB因回弹好、工艺简单,更多应用于制造汽车横梁、纵梁等结构件;TRB在减重性和成形性能均匀性方面更有优势,更多应用于制造车身和航空航天领域.针对目前存在的问题并结合其在汽车工业实践应用的要求,提出了未来变截面薄板成形性能研究和开发的方向.With Comparison, the paper analyzes the forming process of tailor welded blanks （TWB） and tailor rolling blanks （TRB）, evaluates two types of variable section blanks in view of tensile properties, the furmability of hot stamping and the current application. It is concluded that compared with the thickness blanks, TRB and TWB banks＇ bearing capacity can significantly improve, reduce the weight and widely used in automobile lightweight. TWB is widely used in the manufacture of automotive structural parts in the longitudinal beam due to his good rebound and simple process. TRB has more advantages in the aspect of reducing weight and forming uniformity, and widely used in the manufacture of automobile body and aerospace field. Meanwhile, this paper points out the future research and development direction of variable section blanks in view of the existing problems and combined with its practical application in the automotive industry requirements.
