摘　　要：为研究某汽车引擎盖内板在特定定位布局下的法向变形,使用激光扫描仪获取其表面特征,通过VXelements软件对其进行数据化处理,结合Geomagic Studio软件逆向建模构建三维模型,采用NX Nastran软件对三维模型进行有限元分析。结果表明,在特定定位布局下,有限元分析的引擎盖内板法向偏移量与实际偏移量相符。Under a specific location layout,the normal deformation of the automobile hood inner plate is studied.The laser scanner is used to obtain the surface features of the automobile hood inner plate,and the data is processed by VXelements.Combined with Geomagic Studio,a 3D model is constructed by reversing modeling,NX Nastran is used to perform finite element analysis on the 3D model.The results show that under a specific location layout,the normal offset of the automobile hood inner plate of the finite element analysis is consistent with the actual offset.
