摘要:大型曲面外形由于其尺寸较大,开发专用检测仪器设备成本太高,如何高效率低成本地进行大型曲面轮廓精度检测仍是一个亟待解决的难题。根据已有的接触式测量技术,结合飞机大型结构件外形轮廓精度检测的实际需求,探讨利用数控机床和工件测头等加工、检测设备,进行大型曲面外形轮廓精度测量,提出了一种测量方法,并进行了相关仿真和试验研究,验证了该方案的可行性。

Abstract: Because of its large size, the cost of the development of special equipment for testing large-scale curved surface shape is high. How to lower the cost and to increase the accuracy of detection is still a problem Based on the existing contact measurement technology, and combined with the actual needs of the outline accuracy of the large-scale structural parts of the aircraft, this paper uses the existing processing equipment to conduct accurate measurement of the large-scale curved surface profile. The paper puts forward a measurement method and carries out related simulation and experimental research, which verifies the feasibility of the solution.
Key words:large surface;contact measurement technology;structural parts of aircraft
