汽车转向器零部件的逆向工程设计_车辆工程.pdf

摘要:逆向工程是汽车产品开发的一种高效形式，国际汽车界在 20 世纪 90 年代兴起，我 国汽车工业在实行逆向工程已经作了不少工作。逆向工程主要是依靠高度集成化、可视 化开放化的计算机技术和网络技术构筑汽车产品。目前仍需制造样品和样本，进行实物 的试验、论证和评价，但这已经不是一种重要的手段，而最终将会取消这一过程，就思 维的方法而言，思维先于实践，实践反证思维的逆向逻辑形式，国际汽车界称为逆向工 程。

　　　逆向工程技术是测量技术、数据处理技术、图形处理技术和加工技术相结合的一门 综合性技术。处理好这些技术，是逆向工程的一个很重要的环节，其实逆向工程过程就 是处理这些技术的过程，处理好这些技术，制作出来的产品质量也就提高了不少。

　　　本文先讲述汽车转向器零部件数据采集，主要讲述数据采集的基本方法和数据采集 的具体步骤；而后使用 Imageware 软件处理这些采集数据，包括点云的预处理和曲线、 曲面的拟合等；然后使用 UG NX 6.0 软件来构建实体。

Abstract:This is a highly efficient product development form, international auto industry 90 years in the 20th century the rise of reverse engineering in the implementation of China's automobile industry has made a lot of work． Reverse engineering is mainly relying on highly integrated,open visualization of computer technology and network technology to build automotive products Currently manufactured samples and samples needed to conduct physical experiments, demonstration and evaluation, but this is not an important means, but eventually the process will be canceled on the way of thinking, the thinking before practice, practice evidence to the contrary Thinking the form of reverse logic, the international automobile industry called reverse engineering.

　　　Reverse engineering is the measurement technology, data processing, graphics processing technology and processing technology combined a comprehensive technology. Deal with these technologies, reverse engineering is a very important part of the process of reverse engineering is in fact dealing with the process of these technologies, to address these technologies, the quality of produced products also increased a lot.

　　　This article first describes the data collection for steering gear components, mainly about the basic methods of data collection and data acquisition of specific steps; then use Image ware software to deal with these collection data, including point cloud of the Pretreatment and curve and surface fitting, etc.; thenusing UG NX 6.0 software to build entity.
