摘要：Because of the structural stiffness coupling, the vibration responses of wall-mounted vibration damping system are difficult to analyze. Therefore, a research method based on FEM (finite element method) analysis is proposed. The method builds a finite element model of damping system by setting up elastic damping connection parameters. Then thedamping system parameters are obtained by combining vibration reduction tests and vibration theory formula. Finally, the random vibration simulation results are compared with the test results, verifying the feasibility of FEM to study wall-airborne vibration damping system. Based on the finite element method, the effects of gravity center offset and connection position on vibration responses of damping system are studied.
