Abstract

The Herzberg Institute of Astrophysics has developed Integrated Modeling tools for the Thirty Meter Telescope (TMT) project. This simulation software, implemented in MATLAB, models the telescope optical system, structural dynamics, and the segmented primary mirror and secondary mirror active optical control systems. For the TMT project, the integrated model was used to assess the effect of wind loading on the telescope in terms of delivered image quality. The simulation includes a state-space model of the telescope structural dynamics derived from an ANSYS finite element model, a linear optics model derived from a ZEMAX prescription, and wind loading forces derived from PowerFLOW computational dynamics software. The overall complexity of the model necessitates rigorous validation and verification procedures to ensure that the simulation data structures properly represent the original design, and that the calculations performed by the system are reliable. In this paper we discuss the validation and verification of the model data structures, structural configuration, optical configuration, coordinate system transforms, linear optics model, Zernike calculations, and wind loading model. As a case study, we present the verification, validation, and simulation results of the Thirty Meter Telescope Reference Design.
