Today, the quality of air quality is a common concern of all countries, and the universality of automobiles undoubtedly makes environmental pollution even worse. Therefore, how to reduce the vehicle's equipment quality as far as possible, ensure the vehicle's strength and safety performance, reduce the fuel consumption, and thus reduce the exhaust pollution has become the common goal. Because the quality of conventional car preparation is relatively high, it cannot be overestimated when people hear “lightweightâ€. The so-called "lightweight" does not mean to "cut corners, but to optimize the body structure and enhance the strength of materials. Do not look at just such a few words, but its difficulty is not unusual. Why do you say that? Currently, automobiles rely mainly on aluminum alloys, glass fiber reinforced plastic (GFRP) and carbon fiber (CFRP) materials to achieve "lightweight" automobiles. Although aluminum alloy car bodies can theoretically achieve a 30% to 40% weight reduction compared to steel car bodies, the glass fiber and carbon fiber can achieve a higher proportion of lighter weight, but these materials are not only limited by the processing technology, but also by the supply chain. It is also quite small, which leads to high costs, and the number of car companies willing to try is very small. In addition, the manufacturing cost after the implementation of "lightweight" technology is also quite high. Take the body structure, in order to improve the car's "lightweight", we must increase the proportion of aluminum alloy material in the body structure, so that new problems arise, due to the difference between the melting point of aluminum and steel too much , welding together is easy to crack. Engineers are concerned that using traditional methods of riveting or gluing will pose a threat to the safety of people on the vehicle, so they have developed aluminum spot welding technology and achieved fusion welding between aluminum alloy and steel, which has greatly improved the safety of vehicles. . The cost of this technology is also quite high, so it is not possible to apply to all models, but this is only one aspect of “lightweightâ€. If all the items are added together, how difficult it is to imagine Big. Therefore, we should treat "lightweight" with a fair attitude, because it is really not an easy task.
