摘要 基于加权Ashby选材法及车门结构设计关键性能分析,总结了与质量,成本相关的材料效率计算公式,并分别绘制了材料的密度-弹性模量、密度-屈服极限、对数形式密度成本-弹性模量、对数形式密度成本屈服极限Ashby图,通过区域划分建立了相应的评分体系。根据所得材料效率,结合专家评分方法,获得了备选材料库中每种材料子性能的得分以及材料综合性能得分,再根据得分结果选出最佳材料设计方案。结合具体车门外板结构对材料方案进行了抗凹性能验证,结果表明此方法对车门外板的选材设计具有重要的指导意义。 Based on the weighted Ashby material selection method and the key performance analysis of the door structure design,the material efficiency calculation formula related to quality and cost is summarized.The density-elastic modulus,density-yield limit,logarithmic density-cost-elastic modulus,and logarithmic density-cost-yield limit Ashby diagrams were drawn respectively.The corresponding scoring system was established by regional division.According to the obtained material efficiency,combined with the expert scoring method,the sub-performance score of each material in the candidate material library and the material comprehensive performance score were obtained,and then the best material design scheme was selected based on the score results.Combined with the specific structure of the outer door panel,the anti-dent performance of the material scheme was verified.The results show that this method has important guiding significance for material selection and design of outer door panel.
