摘　　要：采用Imageware软件进行汽车仪表板逆向造型设计,对点云处理、曲面重构、精度与光顺性检查等关键技术做了详细阐述。用Hypermesh8.0软件建立了有限元模型,将该模型导入Nastran进行计算,得出仪表板自由状态下各阶振型云图,对云图进行了简要分析,为汽车仪表板的逆向造型与模态分析相结合提供了一种解决方法。Based on Imageware software,this paper describes the detail of the key technologies to deal with point cloud processing,surface reconstructing,precision and light checking for the auto dashboards reverse modeling design.And using the Hypermesh 8.0 software establishes its finite element model,and calculates it with the Nastran software.By the end,we get the frequency of free model in all stages while analyzing the cloud chart briefly for auto dashboards.So,it is a simple solution to research that the reverse modeling for auto dashboards combine with the modal analysis.
