Paper Abstract

The main structure is defined as the telescope mechanical structure including the drives, the encoder system, the hydrostatic bearing system and all those subsystems which make the system self standing safe and testable as an electromechanical system. Since the conceptual design started the main goal was to design a telescope structure with high first locked rotor eigenfrequencies and to eliminate all possible causes of non linear effects on the telescope motion (stick-slip effect in ball bearings and dragging of cable wraps). Moreover the previous experience had shown the superiority from the repeatability point of view of the direct coupled encoders. The paper describes the resulting final design performed by the Italian Consortium AES (Ansaldo GIE-Genova, EIE-Venezia and SOIMI-Milano) which could provide all the features necessary to meet the demanding requirements of ESO's technical specifications.
