The role of the car anti-collision beam

Everyone knows that the triangle is the most stable structure, and the body skeleton is actually composed of many irregular triangles to resist the impact from all directions, but it should be noted that the skeleton of the car is not all places. The same, because it is related to the transmission of force, the collapse, and so on.
 The significance of the front and rear car anti-collision beams is the device for the vehicle to withstand the impact force for the first time. In terms of passive safety of the body, an important concept is that a little force is applied to the whole body. To put it bluntly, a certain position of the car body has been hit. If only this part is allowed to bear the force, the protection effect achieved will be very poor. If the entire skeleton structure is subjected to force when a certain point is subjected to force, the strength of the force on a point can be minimized, especially the front and rear anti-collision steel beams play an obvious role here.
The two ends of the car anti-collision beam are connected with low-speed energy-absorbing boxes with very low yield strength, which are then connected to the vehicle body longitudinal beam in the form of bolts. The low-speed energy-absorbing box can effectively absorb the collision energy when the vehicle has a low-speed collision, and minimize the damage of the impact force to the body longitudinal beam, which can reduce the maintenance cost, and the bolt connection method can be more convenient to replace the car anti-collision beam .

In a high-speed offset collision, the car anti-collision beam can effectively transfer the impact force from the left side (or right side) of the vehicle body to the right side (or left side), allowing the entire vehicle body to absorb the collision energy as much as possible. In the event of a low-speed collision (usually below 15km/h), the car anti-collision beam can prevent the impact force from damaging the front and rear longitudinal beams of the body and reduce maintenance costs.
