In this paper, based on the free damping structure, the damping damping factor of the damping structure is constrained. The complex elastic modulus of the viscoelastic composite structure is obtained, and then the complex elastic constant matrix and the complex stiffness matrix of the viscoelastic composite structural unit body are obtained. It has laid a foundation for calculating the vibration characteristics of the composite structure.
