Control method of tuned mass damper based on rotating inertial effect
ZHANG Yongchun
Abstract：The rotational inertia double-tuned mass damper (RIDTMD) is a novel control device which is composed of tuned viscous mass damper (TVMD) and tuned mass damper (TMD).The RIDTMD is used as the control device,and the vibration control model of multi freedoms structure-RIDTMD is established and the damping effectiveness of RIDTMD is verified.Firstly,the simplified mechanical model of single RIDTMD is established based on the analysis of the operating principle of the RIDTMD device.Then,the control model of multiple DOFs structure with arbitrary number RIDTMDs is established.Next,the H2 norm of the control system is viewed as the optimization goal,and the parameter optimization method of RIDTMD device is put forward.Finally,a three story frame structure is taken as an example to analyze the damping effects and influence rules of parameters of the RIDTMD device on structural response,and the comparison is made with the traditional TMD device to verify the effectiveness and advantages of RIDTMD.
