Research on Wind-Induced Vibration Control of Inertial Mass Damper Based on Wind Tunnel Test
The study of wind resistance of inertial mass damper mainly relies on theoretical analysis and numerical simulation, but lacks experimental verification. For this purpose, an innovative inertial mass damper is designed, whose mechanical topological form is similar to tuned viscous mass damper (TVMD) with mass. The equivalent inertance and damping coefficient of the damper under different working conditions are determined by calibration test. Through wind tunnel test, the influence of various factors on the control performance of the damper is verified. The results show that the control performance is improved when the spring stiffness is close to the optimal frequency ratio. When the damper is installed between the first layer and the second layer, the control effect is the best, and the mode shape difference is the largest at this time. The vibration reduction rate of installed damper is quantitatively analyzed by H∞ design method. These conclusions provide experimental validation for structural wind-induced vibration control in the fields of architecture, civil engineering and hydraulic engineering, fill the gap in the research of inertial mass dampers, and promote the safety and stability research of related engineering structures.
