摘　　要：本文研究目的:归纳关于发动机压气机叶轮叶型曲面造型误差分析的方法;研究方法:通过UG软件比较数据模型和CAD模型的差异来评价模型精度,同时进行曲面光顺性检测来评价模型光滑性能;研究结果:从叶轮叶型曲面造型角度出发,找出误差来源,分析出误差产生的原因,并对叶型曲面进行精度及光顺性检测;研究结论:对于工程应用而言,本文关于发动机压气机叶轮叶型曲面造型误差分析的研究方法是切实可行的。The purpose of this study is to induce the error analysis method of engine compressor blade surface. The model accuracy is evaluated by comparing the difference between the data model and the CAD model through the UG software. At the same time, the detection of surface fairing is made to evaluate the smooth performance of model. Starting from the angle of blade surface modeling, the error sources is found out, the analysis is made on the reason of error generated, and the blade surface accuracy and smoothness are detected. So for the engineering application, the research method on the error analysis of the engine compressor blade surface in this paper is feasible.
