16页汽车仪表毕业设计 篇一:毕业设计论文正文-汽车仪表盘的逆向设计 摘 要 汽车仪表盘不但能反应汽车的造型风格,而且还是汽车上主要的信息显示窗口,能集中、直观、即时、正确地提供汽车在行驶过程中的多种动态情况,让驾驶人员能够经过汽车仪表不停反馈的信息,对汽车进行适时有效的控制:汽车仪表是驾驶人员和汽车进行信息交流和互动的主要界面 大家对美好事物的追求,使得当代仪表盘造型逐步重视美感所以设计出线条优美,曲面平滑,极富动感,由自由曲面拼接而成的仪表盘成为了仪表盘发展的必定趋势同时CAD/CAE/CAM技术的发展和应用,和塑料模具工艺技术的改善,新材料的应用,这些全部对汽车仪表盘的设计提出了新的要求 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怎样更加好的逆向设计出仪表和愈加规范的逆向设计步骤,正是设计者们在主动探索研究的课题 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 car's 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.
