摘　　要： 针对汽车中通道板模型,运用静力分析和优化分析方法,在满足性能要求的条件下,使用复合材料替换金属材料,实现有意义的减重。以结构重量最轻为目标,以金属结构位移作为约束,以铺层厚度为设计变量,得到最优的铺层设计。用HyperWorks软件分析了复合材料代替金属结构位移,对比两种不同材料的有限元分析结果,发现用复合材料的模型,不仅满足强度、刚度要求,而且复材结构质量为1.55 kg,可以实现明显减重比34.6%的减重效果。 Static analysis and optimize analysis is applied to design composite channel plate. The result not only meets the condition, but accomplishes meaningful weight loss. The finite element method is used to optimize ply design with the lightest weight of structure as objective, the node displacement as restrain, the ply thickness as design variable. The displacement of composite structures replaced metal material and analyzed by HyperWorks software demonstrate the structure performance improvement. The way of replacing metal material with composite can meet all demands not only in strength but stiffness. It is found that the optimization result is accord with the request o f structure strength and the structural mass was obviously decreased. The mass of middle channel plate after optimization is 1.55 kg and can be reduced by 34.6% compared with the initial mass of middle channel plate.
