Abstract: |
The measurement principle of laser tracker was introduced, moreover the scheme and the method of the accuracy measurement for assembling the engine of the upper stage were put forward on the basis of the laser tracker. Then the measurement point layout and the transformation method of the coordinate systems in the measurement were explained. At last, the feasibility of the method was verified by the practical application. The measured data met the technical requirements, and the quality reliability of assembling the engine of the upper stage was improved. |
