| Abstract: | An experiment on precision setting measurement of the 65 meter radio telescope back structure is conducted and the result is satisfactory.Aiming at the large size,weight,welding deformation and high geometric precision of back structure,using the total station industrial measurement system,the measurement is rapid,non-contact and high precision,and the point deviation reached 1.0 mm.Using unique construction technology and welding technology to control the welding deformation,the final point deviation is better than 1.5 cm.Control network is established based on design coordinate system to guide back structure installation;the total station instrument additive constant are determined by the TIMS(Theodolite Industrial Measuring System).It is a useful and effective method to detect large antenna back structures due to the actual results. |
| Keywords: | Ф65 meter radio telescope back structure tooling total stations coordinate transformation welding deformation |
