摘　　要：飞机表面某些特殊区域的波纹度会对飞机的气动特性和飞行性能产生较大影响,因此需要精确地掌握这些区域表面的波纹度情况,以便为设计分析和工艺改进提供参考依据。基于三维测量技术,提出一种分析飞机表面波纹度的新方法,该方法借助Max/Exa-scan三维数字测量系统采集飞机表面信息,同时结合CATIA软件数字化分析功能对采集数据进行分析,可以更精确地获得被测区域表面的波纹度情况。工程应用实践表明,该方法在民机设计和制造工艺改进方面具有较高的工程应用价值。Some waviness of aircraft surface in special area will seriously affect the aerodynamic characteristics and flight performance.The waviness of these special areas needs to be measured accurately in order to get reference for design analysis and manufacturing technology improvement.A new analysis method of aircraft surface waviness is proposed,which is based on the 3D measurement technology.In the method,the Max/Exa-scan system is used to get the surface information of an actual aircraft at first.Then the analysis functions of CATIA are used to analyze the waviness of measured area.In the end,an example is given to show the feasibility and effectiveness of this method.
