- Abstract:
- To meet the requirements of roeket sled rails preeision fine-luning measurement, a method based onlaser tracker to precision measurement track geomelry was proposed. The method based on laser tracker to de.teet traek geometry deviations with the slide eontrol network Cpll points as measurement referenee point, u-sing conversion prineiple of spherieal coordinates conversion to spatial Cartesian coordinate system and differ-ent spalial Cartesian coordinate system conversion based on Bursa, proposed to convert the laser tracker systemcoordinates into orbit spaee coorlinates method, and the method was applied to a rocket sled test rail fine-tuning measurement. The results show that this method can meet the design requirements of rocket sled test slidefor fine-luning measurement, and the proposed testing the rocket sled test rail geomelry based on laser traekeideleetion technology is promising for track geomelry fine-tuning measurement of rocket sled test slide rail andhigh-speed test railways with an high elficieney and high aeeuraey statie measurement techniques.
