点云反求造型设计—汽车覆盖件

机械设计制造及其自动化论文，论文编号:JX1268  论文字数:14802.页数:63

 摘要
    本论文主要介绍了怎样进行汽车覆盖件的反求处理和误差分析。首先在反求软件RE-SOFT中对原始数据处理，然后在UG软件中用处理过的汽车覆盖件数据进行曲面造型、组装等，最后得出汽车覆盖件的三维曲面模型。通过产品的逆向流程设计，可以缩短复杂产品加工周期，大大提升了产品设计的效率。随着市场经济的发展，产品或构件的反求工程已经引起社会广泛的重视。针对我国的发展现状，文章提出了反求工程的研究方法，在消化吸收先进技术的前提下，准确地把握该类产品反求的关键技术，最终创造更高的经济效益。综述了反求工程技术的基本概念、应用领域和技术现状，并给出了反求工程技术在汽车领域的一应用实例。

Abstract
      This paper introduces the way to the auto cover's reverse processing and error analysis. In the first we treat the original data in reverse software RE-SOFT and in software UG dealt with the auto cover data which is used surface modeling, assembly, finally we reached the three-dimensional surface model of the auto cover. Through the production’s Reverse Engineering that will reduce the cycle of the product design and enhance the efficiency.With the development of market economy, the reverse engineering of products or components has attracted wide attention. In view of the development of the status quo, the article raised the research methods of the reverse engineering, after the digestion and absorption the advanced technologies, accurate grasp of such products the key technologies of reverse, creating a higher economic efficiency ultimately. Introduct the basic concepts of reverse engineering , applications and technical status quo, and gives a vehicle application examples of the reverse engineering technology in the field .
