毕业设计论文正文-汽车仪表盘的逆向设计.doc

摘 要 汽车仪表盘不仅能反映汽车的造型风格，而且还是汽车上重要的信息显示窗口，能集中、直观、即时、准确地提供汽车在行驶过程中的各种动态状况，让驾驶人员可以通过汽车仪表不断反馈的信息，对汽车进行适时有效的控制：汽车仪表是驾驶人员与汽车进行信息交流和互动的重要界面。 人们对美好事物的追求，使得现代仪表造型逐步注重美感。线条优美，曲面平滑，极富动感由自由曲面拼接而成的仪表。 而其中的逆向设计，因能缩短设计周期降低设计成本，在汽车仪表盘的设计中得到了越来越广泛的应用。逆向设计的软件中，CATIA因其强大的曲面模块和逆向模块，备受设计者们的青睐。如何更好的逆向设计出仪表以及更加规范的逆向设计流程，正是设计者们在积极探索研究的课题。 关键词：汽车仪表盘；信息显示；发展趋势； 逆向设计； CATIA Abstract Car dashboards, not only to reflect the cars styling, but also important information in the car window, focused, intuitive, real-time, accurate delivery of the car in the process of moving a variety of dynamic conditions, so that drivers can continue through the car dashboard feedback, timely and effective control of the car: the car dashboard to the driver and vehicle information communication and interaction interface. The pursuit of better things, making the modern instrument panel shape and gradually focus on beauty. Design beautiful lines, smooth surface, very dynamic, stitched together by the free surface of the dashboard has become the inevitable trend of development of the dashboard. The development and application of CAD / CAE / CAM technology, as well as plastic mold technology improvements, the application of new materials, which are on the car dashboards, design the new requirements. The reverse design, because it can shorten the design cycle to reduce design costs in the design of the car dashboard more widely used. CATIA the reverse design of the software ,because of its strong surface module and reverse modules, much of the designers of all ages. How to better the reverse design of the instrument, as well as more standardized reverse design flow, is the designers to actively explore the research topic.Keywords: car dashboard; information display; trends; reverse design; CATIA 目 录 摘 要 I Abstract II 1绪论 - 1 - 1.1塑料件成型工艺 - 1 - 1.1.1 塑料件的结构设计 - 1 - 1.1.2塑料件成型方法 - 3 - 1.2逆向工程的发展概述 - 5 - 1.3 逆向设计软件CATIA - 7 - 1.3.1 CATIA软件的简介 - 7 - 1.3.2 CATIA的逆向设计模块 - 8 - 1.4本论文研究目的和工作内容 - 9 - 2 汽车
