On-orbit thermal environment-oriented cable membrane truss antenna design method

The invention discloses an on-orbit thermal environment-oriented cable membrane truss antenna design method, and relates to the technical field of radar antenna simulation. The method comprises the following steps: establishing an on-orbit thermal analysis model of the cable-membrane truss antenna; calculating temperature field distribution of the cable-membrane truss antenna when the cable-membrane truss antenna is in different on-orbit positions; establishing a cable-membrane truss antenna optimization design model considering temperature field distribution; and solving the optimization design model to complete the design of the cable-membrane truss antenna. According to the method, the cable-membrane truss antenna thermal analysis model which simultaneously comprises the cable net structure, the thin film structure and the truss structure is established, and the accuracy of an existing cable-membrane truss antenna on-orbit thermal analysis model can be improved; the on-orbit temperature field distribution
