The invention discloses an
energy absorption structure, a cowcatcher device and a railway vehicle, wherein the
energy absorption structure comprises a U-shaped frame and
energy absorption pipes which are made of composite materials, and comprises an energy absorption
pipe front seat and an energy absorption
pipe rear seat which are made of meta; the energy absorption
pipe front seat is fixed on the inner side of the front part of the U-shaped frame, and the two ends of the energy absorption pipe rear seat are respectively fixed with the two
tail ends of the U-shaped frame; the energy absorption pipes are fixed between the energy absorption pipe front seat and the energy absorption pipe rear seat; and moreover, the energy absorption pipe front seat and the energy absorption pipe rear seat are both provided with
metal bosses, and the energy absorption pipes and the
metal bosses are mutually nested and fixed. According to the scheme, the energy absorption requirements of different vehicle types are met by adjusting the number and length of the energy absorption pipes, and the application range is wider; the U-shaped frame made of the
composite material serves as a main body, the energy absorption pipe front seat and the energy absorption pipe rear seat are made of
metal and serve as a framework, and on the basis of certain structural strength, the weight can be effectively reduced; the metal bosses and the energy absorption pipes are fixed in a nested mode, and reliable installation of the energy absorption pipes made of the
composite material is achieved.
