Abstract In order to research the influence by lightweight materials and structures on the performance of anti-collision beams, this paper selected aluminum alloy and carbon fiber as the research objects, this research focused on analysis the different performance on low-velocity impact with open and closed anti-collision beams with these two kinds of material. For the carbon fiber structure, this research analyzed the mechanical pro-perties of it, and established a low-velocity impact model which studied the maximum intrusion, intrusion acceleration and the intrusion force changing along with the changing of time on aluminum alloy anti-collision beams and carbon fiber anti-collision beams during the low-velocity impact with numerical simulation method simultaneously and verified this research with test finally. Study results show that the influence by open aluminum alloy anti-collision beams and carbon fiber anti-collision beams on the fluctuation range of the impact acceleration are smaller than that of the closed aluminum alloy anti-collision beam, and compared with the closed aluminum alloy anti-collision beam, the reduction of maximum intrusion of opening aluminum alloy anti-collision beam and carbon fiber anti-collision beam are 8.2% and 18.6%. During the impact the maximum anti-collision beams force are closed, carbon fiber, opening anti-collision beam in sequence. The test results agreed with the numerical simulation results, and this was further evidence that the research results were reasonable.
