摘要：A test method of rotor space bending axis was put forward. Firstly, for a practical bended rotor, the bending of each section centroid relative to the rotation center can be obtained by using the eddy current displacement sensors, and the bending degree of different sections of the rotor can be obtained in the same absolute coordinate system. Secondly, the cubic spline function was applied to fit the space geometry center line of rotor, and the three-dimensional solid models of the bended rotor were shown by using the OPENGL graphics function, which was called by the Visual C++. Finally, the traditional means of measurement based on the dial indicator were employed to verify the proposed method. The results indicated that, the shaft orbit of each section except for section 1 and section 6 measured by the proposed method were consistent with the shaft orbit of the dial indicator, and circle fitting results were also basically coincident. What's more, the error range of the circle fitting of section 1 and section 6 were in reasonable agreement. Thus the method is available to investigate the migration. © 2017, Editorial Department of Journal of Aerospace Power. All right reserved.
