汽车吸能盒型材生产工艺研究OA

In order to meet the requirement of more effective absorption of collision energy by automotive energy absorbing boxes under low-speed collisions,this paper focuses on studying the influence of factors such as extrusion process and aging process of energy absorbing box profiles on their mechanical properties and energy absorbing characteristics.The mechanical properties and crushing requirements of the energy absorbing box by a trolley are used as evaluation indicators to design and produce energy absorbing box profiles,conduct mechanical performance tests and static compression tests,compare and analyze the mechanical properties and static compression performance results obtained from different process parameters,select the optimal parameters,and obtain a good aluminum alloy energy absorbing box profile.
