• Create part, sub-assembly, and assembly finite element analysis models for sophisticated opto-mechanical gimbals utilizing Femap and NEi NASTRAN. Models are used to determine overall system stiffness, operational deflections due to external loading and thermal environments, and component stresses. • Conduct detailed analysis of carbon fiber composite structures according to MIL-HDBK-17 with Femap, which are used to develop lay-up schedules and specifications. Flexure components analyzed with FEA models and verified with hand calculations.• Develop thermal analysis models with Engineering Equation Solver (EES) considering radiation, conduction, and convection heat transfer both inside and outside of the system. Models are used to determine thermal environment inside the gimbal to ensure electrical and mechanical components will survive and operate under specified ambient conditions.• Wrote and executed test plans to evaluate sealing concepts for drag torque and sealing capability. • Designed drive assemblies for gimbal systems, including interfacing with bearings, motors, encoders. Generated and toleranced part and assembly drawings in SolidWorks to ensure parts would perform as intended.
