Introduction to the relevant knowledge of the car side anti-collision beam

The energy absorption effect of the car side anti-collision beam is mainly related to the following factors:

1. Structural design; this is the most important point. Generally speaking, the energy absorption effect of the hat-shaped anti-collision beam is better than that of the tubular anti-collision beam; in addition, the double-hat-shaped structure is generally better than the single-hat structure; of course, there are also caps. The height of the shape structure, matching with A/B/C pillars, door sills, etc. are all important;
2. The strength of the material; people usually think that the pipes inside are ordinary water pipes, but they are not; the tensile strength of the pipes used in general Japanese and Korean cars is as high as 1400-1600MPA (currently some domestic brand cars use more ordinary pipes) ), is more than 4 times the strength of ordinary pipes, and its energy absorption effect is more than 2 times that of ordinary pipes; and the tensile strength of hat-shaped anti-collision beams commonly found in European and American cars generally reaches 1400MPA;

3. The thickness of the material; of course, the thicker the material, the better the energy absorption effect (regardless of the matching with A/B/C pillars and door sills), the energy absorption effect is proportional to the thickness of the material;
