Research on the identification method of mechanical model parameters of damping wall based on free vibration response was carried out. This paper uses a silicone oil silt mixture as the viscous damping material for damping wall free vibration test based on a single degree of freedom system, introduces the basic idea of mechanical model identification method, and derives the calculation formula of damping force based on the energy method in the analysis of test theory method. In order to filter the high-frequency noise in the velocity time history and damping force time history, Butterworth low-pass filter is designed to filter the data. Draw the relationship curve between speed and damping force, and select the key control points on the curve for fitting to obtain the damping parameters and. Numerical simulation analysis is conducted based on Rosenbrock numerical integration method. The final analysis of the theoretical method is consistent with the experimental results, which shows that the application of the model parameter identification method is good.
