Is the front anti-collision steel beam deformed when it hits? Are the anti-collision steel beams and the car beams connected together?
If the deformation of the anti-collision beam is not serious, the automobile beam is not damaged; However, if the collision beam is seriously deformed, the vehicle beam will also bend and deform. The anti-collision beam is connected with the vehicle beam.

Automobile beam generally refers to the longitudinal beam of an automobile, which runs from the front to the rear.

The anti-collision beam is installed horizontally, and both ends are fixed on the left and right longitudinal beams respectively.

The anti-collision beam of a vehicle is usually curved. When the front of the vehicle is hit, the curvature of the collision beam will be deformed due to the impact force, which will offset most of the impact force.

Not serious impact will only bend and deform the anti-collision beam, but will not affect the main beam; However, if the impact force is large, the deformation of the anti-collision beam can no longer absorb all the kinetic energy, and the remaining impact force will bend the beam inward or to one side.

Therefore, the anti-collision beam is deformed, and the car beam is not necessarily damaged, depending on the degree of car injury.

Extended data:

Anti-collision beam is a device used to reduce the impact energy when a vehicle collides. It consists of a main beam, an energy-absorbing box and a mounting plate connected to a vehicle. Both the main beam and the energy-absorbing box can effectively absorb the impact energy when the vehicle collides at low speed, so as to minimize the damage of the impact force to the longitudinal beam of the vehicle body, and thus play its protective role for the vehicle.

The structure of the anti-collision beam should ensure that the low-speed energy-absorbing box can effectively absorb the energy of low-speed impact through collapse, and the anti-collision beam is connected with the car body through bolts, which is convenient for disassembly and replacement. At present, a layer of foam buffer belt is installed on the anti-collision beams of many vehicles, which is mainly used to support the external plastic bumper when it collides below 4km/h, so as to alleviate the impact force, reduce the damage to the plastic bumper and reduce the maintenance cost.
