Abstract
The present paper presents the concept and integrated modeling analysis of a novel mechanism for supporting segmented dishes for radio telescopes and eventually segmented mirrors of optical telescopes. The concept comprises a novel type of hexapod with an original organization of actuators hence degrees of freedom, with a swaying arm based design concept for the connecting joints between panels/segments, thus achieving an iso-static master-slave active surface concept for any triangular and/or hexagonal panel/segment pattern. The integrated modeling comprises all the multifold sizing and performance aspects which must be evaluated concurrently in order to optimize and validate the design and the configuration: in particular kinematic behavior, dynamic analysis, wavefront error and sensitivity analysis. Some experimental verifications already performed validating single aspects of the integrated concept are also presented with the results obtained.
