论文：汽车和乘员碰撞响应与汽车结构特征的关系的统计分析【中文摘要】通常来说,不同国家的汽车制造商使用不同的设计准则,由此产生的不同的汽车结构设计,但这些车型的碰撞性能和安全等级往往差别不大。对于不同的车型,制造商采用不同的结构设计、车身材料和连接方式,旨在满足不同市场中不同品味消费者的需求。同时,许多设计又会反映制造商的传统、文化和设计理念。它们的共性和个性值得研究。经过多年的技术发展,如今的大多数被测车型表现出很好的乘员保护性能,而不同车型之间的结构设计却有明显的差别。本论文的目标是利用NHTSA的碰撞试验数据库从统计的角度分析试验中汽车碰撞波形、车辆结构特性与乘员碰撞响应之间的相关性。论文从数据库中选择了足够数量的试验,研究正面全宽碰撞试验的碰撞波形,从而评价多种类型车辆的特点并揭示汽车和乘员碰撞响应与汽车特征(如车重、车长、刚度、品牌等)之间的关系。【英文摘要】It is often said that there are specific design guidelines in different countries and for different manufacturers, which lead to different structural designs and largely similar level of crash performance and safety ratings. Manufacturers adopt different structural designs, body mate-rials and joining methods for different vehicle models, aimed at meeting different tastes of customers in different markets. Many designs also reflect manufacturerstraditions, cultures, and design philosophies.
