In the design of the body structure, lightweight has become a major bright spot in the current car. The torsional stability of aluminum has been improved by 34% compared to the previous model, but the weight of the car has been reduced by 3%.
In the design of the body structure, lightweight has become a major bright spot in the current car. The torsional stability of aluminum has been improved by 34% compared to the previous model, but the weight of the car has been reduced by 3%. To expand the proportion of aluminum alloys used in the body, not only the aluminum alloys are used in the hood and front fenders, but also in the large body parts with less stress. The aluminum alloy material after the strengthening process can also be used for local reinforcement of the body structure. For example, the aluminum alloy reinforcement parts in the shape of a honeycomb mesh in the side sills effectively provide protection for side collisions and are lower than steel parts. Weight. In addition, the roof cross member structure is a mixture of aluminum alloy and steel plate, which reduces the weight and improves the rigidity.
