摘要：
Bumper low-speed impact test regulations of different countries were comprehensively analyzed. With reference to the European ECE-R42, the United States Part 581 and Canada CFVSS215 regulations, four kinds of load conditions were proposed to analyze bumper performances at low-speed crash. A finite element analysis method was presented to estimate crash performance of a bumper, and a calculation was carried out for a real car bumper under the four proposed conditions, with maximum longitudinal deformation and energy-absorbing rate as main evaluation indicators. Also, the influence of the bumper thickness on crash performance was investigated, and the results showed that the two-mm-thick beam has the best performance. The calculation and analytical methods and results presented in this paper are helpful for considering crash performances of a bumper at low-speed impact. © 2017, Editorial Office of Journal of Vibration and Shock.
