Tuned mass damper (TMD) device has been a popular vibration control system for moderns as high-rise building, bridge to suppress excessive vibration due to environment or human loading. Moreover, multiple tuned mass dampers have received much attention in the researched. An optimal design theory for bridge implemented with multiple TMD devices is proposed in this paper. The proposed method chooses the objective function with the constraints on the peaks which are at the same heights over frequency ranges of interest. This proposed method successfully reduces vibration of bridge traveled by a car. In a future study, we will extend the optimal design theory for the cases with more than one car and the bridge under seismic loading.

Linear passive vibration absorbers, such as tuned mass dampers, often contain springs, dampers and masses, although recently there has been a growing trend to employ or supplement the mass elements with inerters. When considering possible configurations with these elements broadly, two approaches are normally used: one structure-based and one immittance-based. Both approaches have their advantages and disadvantages. In this paper, a new approach is proposed: the structure–immittance approach. Using this approach, a full set of possible series–parallel networks with predetermined numbers of each element type can be represented by structural immittances, obtained via a proposed general formulation process. Using the structural immittances, both the ability to investigate a class of absorber possibilities together (advantage of the immittance-based approach), and the ability to control the complexity, topology and element values in resulting absorber configurations (advantages of the structure-based approach) are provided at the same time. The advantages of the proposed approach are demonstrated through two case studies on building vibration suppression and automotive suspension design, respectively.

Practical Feasibility

A passive vibration control strategy to mitigate the accelerations of roller batteries in cableways caused by the vehicle transit is investigated. The vibration control strategy makes use of a group of Tuned Mass Dampers (TMDs) placed in different positions along the roller battery. When the frequencies of the TMDs are properly tuned to the modes to control, the energy provided by the dynamic forcing to the roller battery is transferred as kinetic energy to the TMDs. This work investigates the effectiveness of an array of linear TMDs in comparison with the performance of hysteretic TMDs that exploit the restoring forces provided by an assembly of wire ropes. First a dynamical characterization of the roller battery (modal analysis) is carried out. Then an optimization of the assembly of linear TMDs against skew-symmetric harmonic excitations is achieved by means of the Differential Evolution algorithm (DE). Subsequently, the performance of the linear TMDs assembly against the vehicle transit across the tower is assessed. Finally the performance of a network of hysteretic TMDs is studied together with practical feasibility considerations.
