关于汽车结构设计中存在轻量化极限的分析
An Analysis on the Limit of Lightweighting Existed in Automotive Structural Design
【摘要】 针对当前在谋求汽车结构轻量化的实践中,存在片面追求材料高强度、低密度的盲目性,通过理论分析和计算研究了3种截面的梁结构在固支-简支的支承和均布载荷加载的条件下不同减重模式的最大挠度和强度极限,得出了不同截面的梁结构轻量化的极限,可为结构的轻量化设计提供参考。
【Abstract】 In view of the existing blindness of one-sidedly pursuing the use of high-strength and low-density materials in the practice of attempting lightweighting of vehicle structure at present, the maximum deflection and the strength limit of the beam structures with three different cross sections, following different mass reduction modes are studied by theoretical analysis and calculation under a condition of uniformly-distributed loading with a fixed support on one end and a roller support on the other end, to obtain the lightweighting limit of beam structures with different cross sections, providing references for the lightweight design of structure.
