随着汽车需求量不断提高,能源、公害和安全已经成为汽车工业面临的问题,能源问题最突出问题就是如何实现汽车轻量化发展,提高燃油经济性以及提高节能环保,受到能源和环境保护压力,世界汽车工业很早就开始轻量化研究节能手段,同时汽车轻量化水平已经成为汽车工业发展最重要研究课题。轻量化技术不论是对于传统汽车生产,还是对于轿车轻量化设计都成为设计需要考虑因素,最关键问题就是提高对于输出功率、降低噪声、提升操控性和可靠性,汽车做好减少废弃排放。
With the increasing demand for automobiles, energy, pollution and safety have become the problems facing the automobile industry. The most prominent issue of energy is how to realize the development of lightweight vehicles, increase fuel economy, increase energy saving and environmental protection, pressure from energy and environmental protection, The world auto industry has long been lightweight to study energy-saving measures, while the level of lightweight car has become the automotive industry’s most important research topic. Lightweight technology has become a design consideration for both traditional car production and lightweight car design. The key issues are increasing output power, reducing noise, improving maneuverability and reliability, and reducing emissions.
