In this paper, the large-scale annular space deployable truss structure is selected to investigate the dynamic characteristics of the combined structural system under multi-physics coupling conditions. Firstly, using the finite element method, the finite element equation of the transient temperature field of the structure and the basic equation of the optical pressure field are established. Secondly, through simulation and derivation, a variety of load conditions are reasonably designed to obtain the response results of the large truss structure system under different load conditions. Finally, the dynamic behavior of the system is analyzed, and the influence law of force/heat/optical pressure field on the dynamic characteristics of the system is obtained, which could guide the optimal design of large truss structure for space applications.
