摘要
用定量分析的方法,权衡气动性能与乘坐舒适性需求对汽车外形设计的影响。先把汽车车身简化为一个类钝体,并对主要外形特征部位进行参数化。然后选择无轮车身的气动阻力系数和剩余体积百分数作为衡量汽车气动性能和乘坐舒适性的物理量,选取600个以上的性能偏优的样本点,用基因权重函数计算每个外形参数对汽车气动性能和乘坐舒适性的影响程度,并根据综合影响程度进行分类。最后提出能够兼顾汽车气动性能与乘坐舒适性的汽车造型设计建议。
Both aerodynamic performance and ride comfort has important influence on car styling and design. In order to balance them,a quantitative method is studied.First,the principal characteristic of simplified bluff body is parameterized. Aerodynamic drag coefficient and residual capacity percentage of car without wheels are used as quantities to measure aerodynamic performance and ride comfort respectively. Then contour parameters are classified by impact on both aerodynamic performance and ride comfort according to their gene weight value which are based on samples with relatively good performance more 600.Finally,how to balance aerodynamic performance and ride comfort when designing the shape of car is proposed.
