Abstract: In order to reduce accident severity caused by crashes between vehides and barrier terminals,impact test condition and evaluation specification of re-directive crash cushion are brought out based on accident performance and referred to correlative documents in and out of China,and a new type of re-directive crash cushion which meet the evaluation specification is invented by conducting finite element analysis and full-scale impact tests.The results indicate that the re-directive crash cushion is able to absorb kinetic energy of a 1.5 ton car with 60 km/h speed in frontal impact and with 100 km/h speed in side impact.The maximum acceleration direction is 10.7 g in frontal impact and 16.1 g in side impact,and passengers are protected,and the vehicle performance keeps well after crash;The simulation result is coincident with that of test and the error between them is with in 10%.
