摘要：

The Made in China 2025 listed lightweighting as the core and common technology for the development of many key industries. Improving the automobiles lightweighting can effectively save fuel consumption, reduce emissions and reduce pollution to the environment, which is an inevitable trend for the development of the automobile industry. Aluminum alloys are considered to be the material of choice for automotive lightweighting due to its own advantages of light weight, easy processing and molding, energy saving, environmental protection and high recycling rate. In practice, aluminum alloy materials usually need to be bent into a certain shapes in order to match the assembly of the overall structure. However, the springback phenomenon during bending is a serious problem which is difficult to regulate and control. This paper firstly starts from the forming method, geometric, material and process parameters, and combines experimental investigation with finite element simulation, discusses the influence law of these factors on the bending deformation springback of aluminum alloy, reveals the influence mechanism of these factors on the springback of aluminum alloy bending deformation, and provides the theoretical basis for the high precision control of the bending deformation rebound of aluminum alloy. In addition, the prediction and control methods have been reviewed in this paper, which is expected to provide new ideas for high precision springback control during aluminum alloys bending deformation. © 2024 Cailiao Daobaoshe/ Materials Review.
