Drawings
FIG. 1 is an exploded view of a lightweight method of manufacturing an impact beam assembly according to the present invention;
fig. 2 is a side sectional view of a lightweight method of manufacturing an impact beam assembly according to the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the lightweight impact beam structure assembly comprises a GMT impact beam 1, a shell 2, a pedestrian protection bracket 3 and an assembly structure 4. The casing 2 is located before GMT anticollision roof beam 1, pedestrian protection support 3 is located 2 bottoms of casing, assembly structure 4 has 2, and the symmetry sets up 1 both sides of GMT anticollision roof beam. GMT anticollision roof beam 1 is last to be equipped with first mounting hole, casing 2 is equipped with the second mounting hole, GMT anticollision roof beam 1 with casing 2 is through first mounting hole and second mounting hole adaptation connection.
The existing front anti-collision beam is made of materials such as steel plates or aluminum alloys and composite materials. However, after CAE analysis and performance parameter comparison selection, the GMT (glass mat reinforced thermoplastic) material is better than the existing material. The front anti-collision beam prepared by adopting the material through sheet forming and product compression molding has high mechanical property and low density (1/3 of aluminum alloy), has good vibration performance and crack growth resistance, does not crack in a large area under low-temperature impact, and has obvious energy absorption effect.
