Abstract

The invention discloses a diameter expanding and cutting composite type energy dissipation device and a vehicle with the diameter expanding and cutting composite type energy dissipation device. The energy dissipation device comprises a hollow inner ejector rod, an outer sleeve connected with the other end of the inner ejector rod, an axial positioning rod extending into the inner ejector rod, and an axial positioning sleeve located between the inner ejector rod and the axial positioning rod. The energy dissipation device further comprises a cutting tool fixed to the inner ejector rod. The cutting tool is fixed to the inner ejector rod through an inner gasket and a tool reinforcing bolt. A small notch which can enable the cutting tool to cut the outer sleeve is formed in the position, corresponding to the cutting tool, of the outer sleeve. The energy dissipation device has the advantages of being stable, controllable, high in energy consumption, high in specific energy absorption, relatively simple in structure and manufacturing process, and convenient to install.

Description

technical field [0001] The present invention relates to an energy dissipating device and a vehicle, more particularly to a diameter-expanding and cutting composite energy dissipating device and a railway vehicle or automobile comprising the energy dissipating device. Background technique [0002] With the development of railway transportation and the continuous improvement of train operating speed, people pay more and more attention to the safety of train operation. Although the probability of collision accidents of railway vehicles is relatively small, trains running at high speed have greater initial kinetic energy. , once a collision occurs, the loss will be extremely huge. [0003] When a railway vehicle collision accident occurs, due to the need for passive safety protection during the collision process, the initial collision kinetic energy must be completely absorbed or dissipated, and the vehicle structure must meet certain crashworthiness requirements. During the col...
