Abstract:

An upgraded type of tuned mass damper for passive vibration control of structures is developed in this work. This innovative model includes a smaller tuned liquid column damper (TLCD) integrated into a rocker pendulum-tuned mass damper (RPTMD) placed on a smooth-curved surface of the main structure, which is referred to as the upgraded rocker pendulum-tuned mass damper (URPTMD). The URPTMD is a connectionless vibration absorber (CVA) because this design allows it to operate without connection to the main structure. This unique feature is an outstanding advantage of the URPTMD. This leads to easier installation and reduced maintenance costs. After establishing the analytical model of the URPTMD, the results obtained from the parametric studies indicate that the mass ratio between the TLCD and the RPTMD significantly affects the device’s control performance. To explore the vibration reduction ability of this device, the performance of an optimized URPTMD are determined and compared with those of optimal TMD with the same weight. The numerical simulations show that the URPTMD yields higher effectiveness over a broader excitation frequency range compared with a conventional TMD. In addition, the robustness against changes in the structural properties and the mistuning sensitivity of the optimized URPTMD are also investigated. The URPTMD is less robust than the PTMD or TMD when facing changes in both structural stiffness and mass, but the damping sensitivity of the optimized URPTMD is similar to that of the optimized TMD.
