Abstract

This paper describes a random vibration, finite element analysis (FEA), performed on the Gemini Laser Launch Telescope (LLT) using ANSYS. A highly detailed model, originally created for static analysis, served as a baseline model but required extensive simplification to be used for random vibration analysis. A reduced spectrum PSD was also required. This paper describes the simplification process and summarizes the results of the analysis.
