Although the mechanical joint face plays an important role in the field of structural dynamics, few applications of it are found in the design and analysis of space camera structures. The dynamics of two kinds of bolt joint face models are studied mainly. First, two kinds of sample models are established and their parameters are determined according to the spring-damp joint model and the virtual material model theory. The parameters of the spring-damp joint model are determined by combining theory with practice while the parameters of the virtual material model are determined according to the model theoretical formulas. Then, the sample modality of two kinds of models under the finite element condition is compared and analyzed through finite element calculation. Finally, the advantages and disadvantages of two kinds of model dynamics are compared. The result shows that for the spring-damp joint model, the vibration mode fits well with the actual mode while for the virtual material model, the low order natural frequency value fits well with the actual modality. It provides the basis for the application of joint face dynamics models in the analysis of space camera structures.
