AbstractLarge mirror's support position plays a very important role in optical system's wave-front error. This paper took a Φ1.2m diameter primary mirror as an example and introduced the method of integrated opto-mechanical optimization analysis, then structure's parametric model in Proe, finite element's parametric model in Patran, structure analysis in Nastran and opto-mechanical coupling analysis in Sigfit were integrated as a fully automatic process in Isight by use of command streams and result documents produced by these soft wares. After the process was established and verified, automatic gradient searches of primary mirror's optimal support position were conducted using optimizer embedded in Isight. The optimization objective is the minimum of surface error's RMS and the optimization variables are support positions. New searches can easily be conducted repeatedly after mirror's model is modified in the structure parameter document. Because of the search process is fully automatic, manpower and computing time are greatly saved. This example also provides a good reference for problems in opto-mechanical fields. © 2016 SPIE.
