Energy saving and emission reduction is always a subject of endless research. Automobile lightweight is also an important measure for energy saving and emission reduction. Automobile lightweight can not only effectively reduce automobile fuel consumption, but also extend the service life. It also has great benefits for industrial development and people's lives.Lightweight MaterialsThe application and current situation are discussed and the advantages and disadvantages of various materials used in automobile lightweight are analyzed, and the selection of materials in the automobile manufacturing process is supported.

Country6Emission standards are now on the market, and the development of lightweight is getting tighter and tighter. Traditional materials can no longer meet the quality of automobiles.Lightweight MaterialsThe proportion of medium is also increasing. With the continuous improvement of strength and lightweight,Lightweight MaterialsThe research and development and selection are also more important.

Some studies have proved that there is no reduction, and more 0.1T can save fuel.0.6and can also reduce carbon dioxide emissions,11A large number of studies have proved that the lightweight of automobiles is of great help to reduce the consumption of fuel vehicles to meet energy conservation and environmental protection. The analysis of the lightweight effect of pure electric vehicles proves that lightweight can not only save energy, but also increase the cruising range of the car under the same battery capacity and extend the service life of the battery.

From here, we can see that the lightweight of electric vehicles also plays a great role in improving the performance of electric vehicles, and reduces the mass of the car, and can also reduce the burden of the suspension system, reduce the inertia of the car, and protect the vehicle. Lightweight applications such as some new cars can reduce the weight of the vehicle by 25% by using carbon fiber oil crust aluminum connecting rod nylon composite instrument panel and polycarbonate rear window.

Aluminum alloy has been used in automobiles since 189920Century90In the 1990 s, some good sports car used aluminum in automobile manufacturing. The world's first car with an all-aluminum body was Audi's1994Almost all of the materials used in his body, which was developed in, are aluminum, which is nearly heavier than the previous generation's body.35KG.

Plasticization is a major trend in current manufacturing. The quality of plastics for car bodies is higher and the tensile strength is higher, only the weight of ordinary steel.15~20%Lighter wood also has a very large role in promoting lightweight.
