Preliminary research on TMD parameters for swing vibration control of suspended structures
The effect of Tuned Mass Damper(TMD)parameters on the control of suspended structures under in-plane swing motion mode is studied in this paper.Analysis shows that the principles of TMD control and vibration based monitoring by accelerometer for in-plane swing motion mode are unified.At first,simplified calculation models of suspended structures with TMD are developed in different installation conditions.Results show that only the normal TMD is valid in control of in-plane swing motion mode of suspended structures.Then,the simplified calculation model of the suspended structure with accelerometer is developed to analyze in-plane swing motion mode monitoring.The model is similar with that of the sus-pended structures with TMD.As a result,the phenomenon of tangential accelerometer and inclinometer data are zero can be explained.Moreover,a vibration based state monitoring method based on normal acceleration data is proposed.At last,the experiment is carried out to measure in-plane swing motion mode of suspended structures using inclinometer and accelerometer.It verifies the aforementioned theoretical and numerical analysis of control of in-plane swing motion mode of suspended structures with TMD.
