Abstract
To ensure the work of space-borne antenna,the thermal deformation is restricted.Re-ferring to foreign advanced cases and taking care of domestic existing process technology,the ar-ticle puts space-borne parabolic antenna reflector as the research obj ect and designs a new reflec-tor,the core and the skin of which are both made of CFRP.Firstly,the profile error is calculated to reflect the degree of thermal deformation.Then,the influence factor of thermal deformation is analyzed based on orthogonal test.Lastly,on the basis of this,the CTE design of the skin and the core is optimized.The simulation results show that the profile error of the CFRP parabolic antenna reflector designed in this paper is 6 times lower than that is designed before and made of aluminum alloy.The advantage of the CFRP sandwich structure antenna reflector and the reliabi-lity of optimized scheme designed in this paper can be proved based on the above analysis.关键词
