All aluminum passenger car aluminum profiles
The difficulty in designing the all-aluminum structure lies in how to meet the requirements of performance indexes such as rigidity and strength of the whole vehicle, and at the same time realize light weight, form a lightweight aluminum alloy structural frame, and realize a weight reduction of up to 20% compared with the steel structure. At the same time, to meet the performance requirements of the entire vehicle.
For passenger cars with aluminum profiles, the chassis structure must meet the requirements of bending rigidity and torsional rigidity of the whole vehicle as well as fatigue fatigue test of the vehicle to ensure passenger safety. In particular, aluminum is used as a structural part of the body, involving metal joining technology and deep drawing technology, and the technical difficulty is relatively high. Now, the use of aluminum as the chassis structure puts higher demands on the technology.
Increasingly stringent emission standards have placed higher demands on automakers and provided opportunities for the development of lightweight automotive materials. Aluminum alloy is recognized by many bus companies and bus companies as the first choice for new energy buses due to its superior strength, lightweight characteristics, flexible design, high corrosion resistance and high recycling rate.
The lightweight of passenger cars is a systematic project integrating design, manufacturing and material technology. From the beginning of the design, Zhongwang paid attention to structural optimization, continuously carried out material testing and process evaluation, and finally provided aluminum alloy materials with better performance to manufacture all-aluminum passenger cars.All aluminum passenger car aluminum profiles
However, the all-aluminum passenger car has the advantages that the traditional steel body can't match, and it also means that it has significantly improved the difficulty of the body machining process. Zhongwang strictly controls the accuracy and safety of the passenger car with the high-speed rail welding standard to ensure the accuracy and safety of the passenger car. The accuracy of the car body is higher than that of the steel car, and the light weight target is better achieved.
