Structural, Thermal Optical Modeling of CUBESAT GEO Based Orbit Camera Payload 14th annual Advanced Maui Optical and Space Surveillance Technologies (AMOS) Conference, September 10-13,2013, Maui, Hawaii Manuscript Number 1203299

摘要

This paper presents the results of a team of students at California State Polytechnic University at Pomona (Cal Poly Pomona) who have been working on a multi-disciplinary team capstone senior project sponsored by Caltech's NASA Jet Propulsion Laboratory (JPL). Results obtained from Structural, Thermal Optical (STOP) Modeling of a CUBESAT GEO based orbit instrumentation payload using SIEMENS PLM NX Space Systems Thermal and NX NASTRAN Finite Element Analysis (FEA) tool suite is the focus of this paper. Results from environmental loading used to predict the thermal performance of a 4U-CUBESAT instrument payload composed of and IR camera surveillance based sub-system are presented. These thermal predictions are used to perform top-level STOP analysis in order to form an optical Figure of Merit (FOM) parameter for performance characterization.
