An energy-absorbing anti-collision device for a high-speed maglev train

Abstract

The invention relates to an energy-absorbing and anti-collision device for a high-speed maglev train, which includes an external structural box and fillers arranged inside; wherein, the external structural box includes: a front beam; several main energy-absorbing boxes, each main One end of the energy-absorbing box is respectively arranged vertically and side by side on the front beam; the transverse connecting beam is connected and arranged between the other ends of the adjacent main energy-absorbing boxes. The energy-absorbing anti-collision device for high-speed maglev trains adopts a completely different structure from the existing devices, and uses energy-absorbing fillers. It has large energy-absorbing capacity, small post-collision acceleration, light structure weight, and safety protection performance for passengers. Good advantages; the structure is light and novel, and the practicability is strong.

Description

technical field [0001] The invention relates to an anti-collision device, in particular to an energy-absorbing anti-collision device for a high-speed maglev train. Background technique [0002] At present, the front of the high-speed maglev train used in the maglev demonstration line is equipped with a kind of anti-collision box. The kinetic energy is consumed, and the impact kinetic energy can be absorbed to protect the safety of the occupants in the event of a collision between the vehicle and a large foreign object on the track beam. [0003] But above-mentioned anti-collision box has following shortcoming and deficiency: [0004] 1. The connection strength between the beam and the longitudinal beam of the crash box is weak, and it is difficult to withstand the relative impact force of a large obstacle. When a collision occurs, failure occurs earlier and longitudinal loads cannot be transmitted. [0005] 2. The main energy-absorbing box of the anti-collision box is arr...

AI Technical Summary

Problems solved by technology

[0004] 1. The connection strength between the beam and the longitudinal beam of the crash box is weak, and it is difficult to withstand the relative impact force of a large obstacle

When a collision occurs, it will fail early and cannot transmit longitudinal loads

[0005] 2. The main energy-absorbing box of the anti-collision box is arranged horizontally, but due to the premature failure of the above-mentioned beams and longitudinal beams, the kinetic energy absorbed by the impact will not be transmitted to the main energy-absorbing box, so it is difficult to play its due role. effect
