For example, for a vehicle with a gross vehicle weight (GVM, Gross VehicleWeight) of 3125kg, the thickness of the upper plate 101 of the anti-collision beam and the lower plate 102 of the anti-collision beam are designed to be 2mm-3mm, and the thickness of the upper plate connecting portion 1011 and the lower plate connecting portion 1021 Designed to be 4mm-6mm, the thickness of the anti-collision beam side plate 103 is designed to be 3mm-5mm, and the thickness of the anti-collision beam reinforcement plate 12 is designed to be 2mm-3mm.

The corresponding plate thickness can be adjusted in a certain proportion according to the total vehicle weight. For example, when the total vehicle weight is 2100kg, the corresponding plate thickness can be designed according to a proportional factor of 0.9 times the plate thickness of a vehicle with a total vehicle weight of 3125kg. It should be noted that the anti-collision beam upper plate 101, the anti-collision beam lower plate 102 and the anti-collision beam reinforcement plate 12 belong to the weakening center of the anti-collision beam body 10 which is more easily deformed during collision. In order to meet other working conditions, CAE simulation can also be used. Analyze and design the actual crash test and adjust the thicknesses of the above-mentioned corresponding plates, upper plate connecting portion 1011 and lower plate connecting portion 1021.
