Abstract

The invention relates to the technical field of railway vehicles, in particular to a railway vehicle and an energy absorption device thereof. The energy absorption device comprises an energy absorption part which is made of a fiber reinforced composite material, one end of the energy absorption part is installed on the railway vehicle, and the energy absorption part is used for absorbing energy through brittle fracture smashing in the collision process. The energy absorption device has the advantages of being small in size, light in weight and small in occupied space, and the problems that anexisting energy absorption device is large in size, heavy in weight and large in occupied space can be solved.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular, to a rail vehicle and an energy absorbing device thereof. Background technique [0002] With the rapid development of high-speed trains, the operating speed of rail vehicles such as EMUs is also increasing, and the safety of rail vehicles has attracted more and more attention. The energy absorption during the collision process is the key to ensuring the safety of rail vehicles. Therefore, it is necessary to add an energy-absorbing device at the end of the rail vehicle to absorb part of the huge energy generated during the collision, thereby greatly increasing the passive safety of the rail vehicle. [0003] During the collision process, the existing energy-absorbing devices absorb the collision energy through the plastic deformation of the energy-absorbing parts made of metal materials. Due to the low specific energy absorption (SEA) of metal materials, the existing...
