基于敏度分析的可展开桁架刚度优化设计
Optimization Design of Deployable Truss Stiffness Based on Sensitivity Analysis
摘要
Abstract
Deployable truss is the key component of SAR satellite mission,and its performance di-rectly affects the imaging quality of the satellite.At the same time,in order to reduce the influ-ence of deploying on the satellite,the specific stiffness of the deployable truss should be as large as possible.The deployable truss stiffness optimization method is proposed based on the sensitivity analysis of the GF-3 SAR antenna hinge stiffness to deployable truss stiffness optimi-zation.On this basis,using this method multi module deployable truss expanded state stiffness is optimized.关键词
