课程描述:

Course Description:

严格的法规和NCAP评估使汽车的碰撞性能成为汽车开发的重要指标之一。所以这就迫使汽车设计者必须具备良好的车身结构及相关碰撞知识。而只有当这些知识和现代设计合并的时候才能在汽车开发时少走弯路、使理论发挥最大的作用。本课程的目的是通过一些成功案例来介绍汽车开发的有效方法。

本课程由以下几部分组成：首先是碰撞现象的描述方法的介绍；其次是最新汽车设计工具（CAD/CAE）的介绍；最后是介绍典型的成功案例，通过这些案例分析了这些设计的开发思路以及实现设计目标所采用的一些具体手段。同时还介绍一些汽车结构设计中常用的优化方法。

Stringent legal and consumer-protection requirements around the world have made crashworthiness one of the most important requirements in automotive development. Therefore it is mandatory that designers have a good understanding of the crash behavior of mechanical structures. The combination of knowledge about mechanics and the ability to use modern design tools allows for an efficient development process without unnecessary design iterations. The objective of the seminar is to present current methods and successful solutions for crashworthy car body design.

At the beginning of the course the mechanical phenomena of crash events will be discussed. Subsequently modern development methods (CAD design and crash simulation) will be treated. Finally the course will present solutions of current vehicles and demonstrate how the crashworthiness design has been successfully employed in these vehicles. Mathematical optimization technologies for structural design – which are increasingly used in industry – will be covered at the end of the course.
