Design and optimization of reflector bracket for moving mirror IRST

doi:10.7523/j.issn.2095-6134.2011.2.004

Abstract

Abstract:

We designed a bracket structure by request of some complex IRST. The aim of the structure optimization was to minimize the mass and moment of inertia. We completed the optimization and analysis in which we took the plane axis thickness as a variable and imposed restrictions on the mode frequency and deadweight distortion. The results show that the bracket mass reduces from 0.62kg to 0.38kg and the moment of inertia reduces from 0.0098kg ·m² to 0.0056kg ·m².

Key words: IRST, reflector bracket, structure design, finite element analysis, structure optimization
