课程描述:

Course Description:

汽车的车身担负着承载人员等重要的功能，它必须满足一系列法规和NCAP的要求。本课程详细介绍了这些要求并讲解了如何将这些要求分解到车身的主要部件和子系统，以满足车身的设计要求。本课程还详细讲解了车身设计的基本原理和要求，即主要负载工况的获取、车身构造分析、各部件材料选择、连接方式及技术、以及详细的开发过程的分析。

本课程还将对车身耐撞性、典型的静动态工况分析过程作详细介绍。并针对目前一些成功的车身设计案例进行分析和介绍。对车身设计的优化过程及试验步骤等做些简单介绍。

Automotive car bodies are subject to numerous functional, legal and consumer-driven requirements. The course presents the major requirements and identifies the main body components and modules and their major functions. It discusses the fundamental principles of car body design - load carrying principles, body architectures, material selection, joining techniques and details the phases of the development process.

An emphasis of the course will be on the analysis procedures employed in designing static and dynamic properties and crashworthiness characteristics.

Finally the course will present solutions of current vehicles and demonstrate how the design principles discussed have been successfully used.

A walk-through on optimization technologies and testing procedures will conclude the course.
