Anti-explosion impact crushing energy-absorbing beam at bottom of vehicle

Abstract

An anti-explosion impact crushing energy-absorption beam at the bottom of a vehicle (3) comprises a front beam (5), a side beam (6), an installation support (7), a front beam crushing energy absorption box (8), a side beam crushing energy absorption box (9), foamed aluminum (10) and a bolt b (11). The anti-explosion impact crushing energy-absorption beam is characterized in that the front beam (5)is preferably an aluminum alloy rectangular bent pipe beam, is filled with foamed aluminum, is in contact with the bottom armor, plays a role in deforming the bottom armor and absorbing part of explosion impact energy to crush the energy-absorbing beams (3), and is mounted on the chassis girder (1) through bolts a (4) and uniformly distributed; when a vehicle is exploded, the multi-stage buffering and crushing energy absorption effects can be generated, most of energy acting on the bottom lightning protection armor is absorbed, and uploading of the energy is reduced; and the strain of the bottom armor is reduced, so that the lightning protection performance of the vehicle is improved, and finally the effects of protecting passengers and improving the survival rate of the passengers are achieved.

Description

technical field [0001] The invention belongs to the technical field of wheeled anti-mine anti-ambush vehicles, and in particular relates to an anti-explosion shock crushing energy-absorbing beam at the bottom of the vehicle. Background technique [0002] Since the outbreak of the Iraq War, various improvised explosive devices (IEDs) have posed a serious threat to the safety of vehicles and occupants. has become a research hotspot in this field. [0003] At present, the lightning protection of vehicles mainly adopts the addition of lightning protection armor at the bottom of the vehicle. Traditional lightning protection armor is generally installed directly on the vehicle frame or the bottom of the vehicle body, and there is no relevant buffer energy absorption transition design at the installation connection position. [0004] Although the anti-vehicle mine protection technology at the bottom of the vehicle can prevent the bottom of the vehicle from being penetrated by expl...

AI Technical Summary

Problems solved by technology

[0004] Although the anti-vehicle mine protection technology at the bottom of the vehicle can prevent the bottom of the vehicle from being penetrated by explosives, the data obtained from anti-terrorism and peacekeeping missions show that the damage caused by anti-vehicle landmines and improvised explosives is still on the rise, because vehicles are exposed to such In the event of such an attack, the rigid transmission of the bottom armor is impacted on the girder or the vehicle body, causing the passenger compartment to absorb a large part of the energy, which eventually leads to a great increase in the damage of the occupants of the vehicle
