| Abstract: | Due to the high price of road crash cushion,a buffer with thin-walled tube beam energy absorption principle absorbing beam was designed through computer simulation studies to determine the energy absorption of a single beam energy absorption capacity;energy absorption and the skeleton of beams can be assembled into a highway fender-oriented;the fender could be driven with a function and adjusted as the number of energy-absorbing beam group to meet requirements of different vehicle collision speed and the maximum degree of protection for the passengers to safety.Compared with other similar products at home and abroad,it had obvious cost advantages. |
