为实现发动罩盖的轻量化设计,本文使用铝合金材料制作发动机罩盖。基于刚度和行人保护,利用OptiStruct软件优化设计一种新型的铝合金内板结构,相比原钢制罩盖,重量减轻46.4%,行人头部保护、刚度和模态性能没有降低。
為實現髮動罩蓋的輕量化設計,本文使用鋁閤金材料製作髮動機罩蓋。基于剛度和行人保護,利用OptiStruct軟件優化設計一種新型的鋁閤金內闆結構,相比原鋼製罩蓋,重量減輕46.4%,行人頭部保護、剛度和模態性能沒有降低。
위실현발동조개적경양화설계,본문사용려합금재료제작발동궤조개。기우강도화행인보호,이용OptiStruct연건우화설계일충신형적려합금내판결구,상비원강제조개,중량감경46.4%,행인두부보호、강도화모태성능몰유강저。
In order to realize the engine hood lightweight, the authors use the aluminum alloy materials to make the engine hood. Based on the stiffness and the pedestrian protection, they apply the OptiStruct optimization software to design a new type of inner aluminum alloy plate structure. Comparing the original steel hood, it reduces weight 46.4%, and the pedestrian head protection, stiffness and modal performance are not lower.
