设计简介
摘 要
伴随着社会科技的不断前进，现代汽车车身造型设计也在迅速变革与发展。人机工程学、空气动力学和现代化制造方法的发展促使汽车车身造型的不断更新和完善，传统与创新艺术风格的有机结合也影响着车身总布置的美学实践。然而，每一款新车型的问世都离不开车身造型和它的设计工具，汽车车身布置设计是汽车概念设计阶段的一项相当重要的方案设计工作。
本次设计首先从车身造型设计的研究的意义、研究的任务，研究的方法及未来车身开发的前景进行阐述。并对传统的车身造型设计和现代车身进行了比较说明。
本次设计主要内容是根据人机工程学的理论和在汽车上实际应用的分析，进行车身前后围进行了设计。三维设计软件对于提高车身总布置的质量效率缩短产品开发周期具有非常大的现实意义。
关键词：前后围；人机工程学；车身
Abstract
Follows the social science and technology unceasing advance, the modern automobile body is always arranging also in the rapid transformation and the development.The man-machine engineering, the aerodynamics and the modernized manufacture method development urges the unceasing renewal and the consummation which the automobile body always arranges, traditional and the innovation artistic style organic synthesis is also affecting esthetics practice which the automobile body always arranges.However, each section new vehicle being published cannot leave the automobile body always to arrange and its design tool, the automobile body total arrangement is an automobile conceptual design stage quite important project design work.
This design first from the automobile body modelling design research significance, the research duty, the prospect which the research method and the future automobile body develop carries on the elaboration.And always arranged the design and the modern automobile body to the traditional automobile body has carried on the comparison explanation.
This design primary coverage is according to the man-machine engineering theory and on the automobile the practical application analysis, carries on always arranges the design.This article introduced the automobile always arranges the design tool manikin, the eye ellipse.Proposed the overall evaluation pilot comfortableness, the field of vision, leg department factor and so on operation space, steering wheel, roof panel H region law. CAXA regarding enhances the quality efficiency reduction product development cycle which the automobile body always arranges to have the extremely big practical significance
Key words：Before and after the circumference；Ergonomics； Auto-body
