As square tube type protective device as the object, selected on the basis of the results of the simulation test, design the crossbar and arm structure plan of the six groups of different wall thickness. Through bus rear-ended dangerous goods transport vehicle simulation test way, analyzes the deformation and energy absorption about the bus and six groups of protective device which has different wall thickness. Research results show that the main energy absorption part of square tube type protective device is the arm structure. The optimal design scheme is when the wall thickness of the arm is 4 mm and the wall thickness of the crossbar is 3 mm.
