In the body mechanism, the energy absorption capacity of the filling structure is greater than that of the energy absorbing box and the aluminum foam, and because of the isotropy of the aluminum foam, it can also absorb energy very well in the offset collision. With the improvement of people's safety awareness, the concept of pedestrian safety has gradually taken shape. This structure can absorb all the energy of vehicle impact at 15Km/h speed, and it can protect the safety of pedestrians.
1, NVH heat absorbing sound insulation, foam aluminum can also play an immediate effect. For example, it has been used in bus silencers.
2, bus foam muffler, foam aluminum sound absorbing board after fire treatment, can be applied to the temperature of the tail gas near 600 degrees. The noise reduction effect is 2-3 times of that of impedance type and parallel resonance type mufflers, and the weight is reduced by about 1/3. Besides, the floor, spacer and door sandwich panels made of foam aluminum can also achieve sound insulation and shock isolation.
3. As the largest coverage on automobiles, how to synthesize the requirements of weight and strength has always been a headache for manufacturers. The thickness of foam aluminum sandwich panels is only about 2mm, the rigidity is 7 times that of the steel ceiling, and the weight can be reduced by more than 50%.
