The invention discloses a thermoset coupling structure dynamics order reduction model method suitable for thermodynamic elasticity analysis and belongs to the technical field of aerodynamics. The method comprises the steps of S1, performing order reduction on a structure temperature field, constructing a structure temperature field order reduction model, and obtaining a structure temperature fieldlow-order vector after order reduction of the structure temperature field at any moment; S2, selecting a modal shape of a reference structure as a reference modal shape phi ref, and performing orderreduction on a deformation field to obtain a low-dimensional vector q based on phi ref; s3, establishing a kinetic equation of the heated structure; s4, establishing a thermosetting coupling kinetic model of the heated structure; sampling is carried out in the q and the formed L + N-dimensional space; a series of sample working conditions with different deformation field and temperature field loads are obtained, M, D and K (1) in a formula (7) are identified through a system, and nonlinear structure dynamics analysis under a time-varying temperature load is carried out after training is completed, so that a thermosetting coupling dynamics model based on a neural network is a nonlinear model and has generality.
