This paper summarized the development of dynamic model improvement methods, and researched the refinement methods based on frequency and response functions, which had been developed in recent years. In order to make the full use of the frequency and response functions obtained in the vibration test, the paper introduced three dynamic model improvement methods with frequency and response functions such as residual method, design parameter method, method of perturbation and so on. The paper may supply useful reference to the development of the spacecraft model’s updating technology.
