ABSTRACT In this paper， the quasi-static crushing test and simulation analysis of the thin-walled tube in the anti-climbing buffer device are carried out. Compared with the metal thin-walled tube， the composite thin-walled tube can reduce weight by 40% and increase specific energy absorption by 17%. The composite thin-walled tube assembly is applied in the anti-climbing buffer device， and the preliminary design and simulation are carried out. The overall structure can effectively reduce the mass， improve the energy absorption efficiency， and better protect the life safety of passengers.
