Question

随着科技水平的不断提高和计算机技术的迅速发展，计算机三维造型技术尤其是逆向工程技术在工业上已经得到了广泛的应用。本次设计以风行商务车的仪表板中央控制面板（中控板）为研究对象，研究仪表板中央控制面板外形的逆向工程造型方法，并对逆向工程概念、方法进行系统的阐述。首先，通过柔性关节臂测量仪扫描获取仪表板中央控制面板表面的点云数据，然后利用Imageware软件对点云数据进行处理，最后通过UG NX6.0应用软件基于曲面重构理论进行仪表板中央控制面板造型表面重构，最终实现了仪表板中央控制面板的曲面重构，产生其三维模型，并通过三维模型设计出适合生产的注塑模具。UG NX6.0的重构设计方法主要通过分层好的点云作线条，并通过线条网格、扫掠以及曲线组等方法作出曲面，再通过面以及面与面间的修剪，做成仪表板中央控制面板的外形片体，最后，对片体进行片体缝合成实体。然后运用边倒圆等优化实体，使实体的线条形体变得更美观流畅，各部件设计简洁明了，从细节上反映该产品的美观性、方便性与实用性。与传统的正向设计方法相比，逆向设计方法提高了工作效率，缩短了新产品的开发周期。

Answer 1

With the improvement of science and technology and the rapid development of computer technology, computer 3 d modeling technology, particularly the reverse engineering technology in industry has been widely used. The design for the popular commercial central control panel (the instrument panel control board) as the research object, and study the central control panel dashboard appearance reverse engineering modelling methods, and reverse engineering concept, methods of the system in this paper. First, through the flexible joint arm measuring instrument scanning for the central control panel of surface panels point cloud data, and by using the software of Imageware point cloud data processing, and through the NX6.0 UG software application based on surface reconstructing theory of the central control panel modelling dashboard surface reconstruction, and finally achieve the instrument panel of the central control panel surface reconstruction, produce its 3 d model, and through the 3 d model design is suitable for the production of injection mold. The reconstruction of the NX6.0 UG design method mainly through the layered good point clouds line, and through the line for grid, sweeping and curve method such as group to curved surface, again through the surface and surface and surface of the clip, made between the central control the appearance of the panel dash of block, finally, to block for block suture into entity. Then use edge down round, etc, make the entity optimization entity lines form become more beautiful and fluent, all the parts design concise details, reflecting the product beautiful sex, convenient and practical. And the traditional design method is compared, reverse design method improves the work efficiency, and the shorter the new product development cycle.

Answer 2

With the continuous improvement of science and technology and the rapid development of computer technology, computer three-dimensional modeling technology of reverse engineering technology in industry in particular has been widely used. The design of the popular business car dashboard central control panel (control panel ) as the research object, research the dashboard central control panel contour in reverse engineering modeling method, and the concept of reverse engineering, method is introduced. First of all, through the flexible articulated arm measuring instrument scanning dashboard central control panel surface point cloud data, then using Imageware software to the point cloud data processing, finally through the UG NX6.0 application software based on surface reconstruction theory of dashboard central control panel moulding surface reconstruction, finally achieve the dashboard central control panel surface reconstruction, to produce the3D model, and through the3D model design for the production of injection mold. UG NX6.0reconfiguration design method mainly through stratified good point cloud as lines, and through the line grid, sweep and the curve group and method of making curved surface, and through the surface and surface and surface trimming, a dashboard central control panel shape sheet body, finally, on the body piece sewed the entity. Then use the edge chamfering and optimization of entity, the entity form becomes more beautiful and smooth lines, each component design concise, from the details of the product appearance, convenient and practical. Compared with the traditional design methods are compared, the reverse design method to improve the working efficiency, shortens the development cycle of new products

Answer 3

Along with the technological level unceasing enhancement and the rapid development of computer technology, computer three-dimensional modelling technology, especially the reverse engineering technology in the industry has been widely used. This design with popular central control panel of MPV dash control board) (dash as the research object, the central control panel shape modelling of reverse engineering and the methods to reverse engineering concept, methods systemic explanation. First, through the flexible joint arm measuring instrument scanning access the control panel surface dashboard central point cloud data, then use Imageware software to point cloud data processing, finally through NX6.0 application software UG based on surface reconstructing theory central control panel modelling dashboard, and finally achieve the surface reconstruction dash soft-wares of central control panel, produce its 3d model, and designed by 3d models suitable for the production of injection mold. UG design method for the reconstruction of the NX6.0 mainly through stratified good point clouds, and through the line for line grid, sweeping and curve method such as surface, made of surface and surface and by again face the clip, made between the appearance of central control panel dash of block, finally, to block for block stitched into entity. Then use edge roundingoff, etc, make the optimized entity body become more solid lines fluent, each component design beautiful short and concise, reflecting the products from detail the beautiful sex, convenient and practical. And the traditional top-down design method, the reverse design method compared improves the work efficiency, shorten the new product development cycle.
