摘　　要：逆向工程技术作为一种先进的快速成形与仿真分析技术,目前已广泛应用于装备制造领域。为了对一些尺寸较小的关键零部件进行快速仿形与二次开发,针对某超音速薄壁管件的形状特点,利用逆向工程的方式建立流程与搭建平台,对其开展三维扫描、尺寸测量、点云修复及逆向建模等工作,并将最终获得的三维实体模型代入到分析软件中进行超音速流体域加载。通过对薄壁管件的内外流场分析,实现了对管口结构的初步优化,有助于提高其长期运行寿命。基于逆向工程技术对该超音速薄壁管件进行了全流程的仿形与模拟,建立起一套完整的针对体积较小零部件的逆向建模流程、流场仿真分析与优化设计方法,为后续表面形状更加复杂的流体域零部件二次设计与优化奠定了基础。As an advanced rapid prototyping and simulation analysis technology,reverse engineering technology has been widely used in the field of equipment manufacturing.In order to carry out rapid profiling and secondary design for some key components with smaller size,according to the characteristics of a supersonic thin-walled tubular part,the 3D scanning,dimension measurement,point cloud repairing and reverse modeling were carried out through establishing a process and platform by reverse engineering,and the final 3D model was substituted into the analysis software for supersonic fluid domain loading.Through the analysis of the inner and outer flow fields of thin-walled tubular parts,the preliminary optimization of inlet structure was realized to improve its long-term operating life.Based on reverse engineering technology,the whole process of modeling and simulation of this part was carried out,and a complete set of reverse modeling process,flow field simulation analysis and optimization design methods for smaller parts were established,which laid the foundation for the secondary design and optimization of fluid domain parts with more complex surface shapes.
