涡轮叶片模具三维模型重构及误差分析

摘要

An error inspection method based on 3D Model Reconstruction is proposed for estimating the manufacturing error of turbo blade mold. Two 3D models (design model and measurement model) are constructed by design data and measurement data respectively. The design model can provide theoretical evidence for error inspection. The quantitative manufacturing error will be obtained through these two models. The outcomes of this research can be utilized in analysis of digital inspection and error analysis.%为了得到涡轮叶片模具制造误差量化分析结果,提出基于模型重构技术的误差检测方法.分别根据理论设计数据和实物测量数据建立了涡轮叶片模具的三维设计模型和实物模型,设计模型将为误差分析提供理论依据,通过两个模型配准和型面误差分析,得到量化制造误差.研究结果可用于类似的零件的数字化检测和误差分析.
