Abstract

Under the background of dual carbon policy as well as energy conservation, blanks with variable thicknesses (BVTs) which act as structural components have drawn extensive attention due to their excellent strength and formability and reasonable load-bearing distribution characteristics, particularly in the field of automotive manufacturing. With these advantages, the manufacturing technologies of these plates using more efficient rolling methods have thus emerged. This article summarizes four methods and their characteristics for manufacturing plates with variable thicknesses based on rolling technology. In addition, a review is conducted on the latest research progress of the metal flow and rolling theories of existing plates with different thicknesses in the longitudinal and transverse direction.

摘要

在双碳政策以及节能的背景下，作为结构部件的变厚度板（BVTs）因其优异的强度、可成形性和合理的承载分布特性而受到广泛关注，尤其是在汽车制造领域。基于这些优势，采用更高效轧制方法制造这些板材的技术应运而生。本文总结了基于轧制技术制造变厚度板材的四种方法及其特点。此外，还对现有不同厚度板材在纵向和横向方向上的金属流动和轧制理论的最新研究进展进行了综述。
