中文摘要
背景:汽车工业面临着提高燃油效率和减少温室气体排放的严峻挑战。车身结构的轻量化已成为应对这些挑战的重要场所。提出了一种新的轻量化车身设计方法。这种设计模式是基于结构的荷载传递能力,而不是基于应力。这种能力是由一种新的数学度量--负载路径指数(U*)来表征的。U*设计范式补充了传统的基于应力的设计,但通过考虑荷载传递增加了一个新的维度
英文摘要
BACKGROUND: Automotive industries are facing severe challenges to improve fuel efficiency and to reduce greenhouse gas emission. Weight reduction in vehicle body structure has become an important venue to address these challenges. A new paradigm for designing light-weight vehicle bodies has been developed. Such a design paradigm is based on the load-transferring capacity of the structure rather than the stresses. Such a capacity is characterized by a new mathematical measure, Load Path Index (U*). The U* design paradigm complements the traditional stress-based design, but adds a new dimension by considering the load-transferring
