abstract="The bumper beam plays an important role in protecting passengers and vehicles from the injury and damage that can be induced by a severe collapse. Many studies on automotive weight reduction have investigated material substitution, structure optimisation and filling foam material. This paper proposes a new optimisation method in which the material, main section shape of a component can be linked to each other and in which the main section shape changes with the material. This new methods is used to create a lightweight optimisation design for a frontal bumper system. It is a better optimisation solution, and the effect of being lightweight is obvious. The bumper system mass reduction is 1.4 kg, and the weight-loss ratio reaches 25.74%. Except for the peak acceleration of the left and right B pillars, the frontal impact performance of the car is better; the peak acceleration rates of the left and right B pillars decrease by only 1.81% and 2.84%.<p /> <p>Language: en</p>",
