Abstract
Based on the numerical method,the work of optimizing composite crossed beam structures in spacecraft was conducted in this paper.The load-transferred path was optimized depending upon the load-bearing structure components.Furthermore,the enhanced region and lay-up of T700 unidirectional carbon/epoxy prepregs were reasonably presented,while the specimen was fabricated integrally by manual molding technology.The experimental results demonstrate that the weight of this crossed beam is reduced from 966 g to 436 g,up to 37.5％;the maximum deformation is reduced from 0.33 mm to 0.19 mm under the 6000 N compressive load,which satisfied the stiffness demand.关键词
