摘　　要：通过层析的方法,运用Imageware和UG软件,对某型4缸发动机气缸盖气道模型进行了CAD重构。通过气道模型的重构,探索了基于层析法的曲面内腔类零件的反求设计方法。对层析法反求设计的点云数据测量、数据处理、气道重构等技术进行了研究;提出了对气道类形状,采用曲线截面的方法得到不同截面的轮廓线,再进行扫掠,是一种误差较小的模型重构方法,对类似形状零件的反求设计有参考意义。The airway model of engine＇s cylinder head is reconstructed by CAD through slicing method and using Imageware and UG.The reverse design methods used for complex interior structure＇s surface are explored based on slicing method through remodeling the airway.The technologies of reverse design such as the measure method of points cloud,points cloud data treatment,and airway modeling are studied.For remodeling the shape like interior airway,it is a better way to use curve section to get different section contour line,and then sweep.The methods can be reference for similar parts reverse design.
