✦ Synopsis

This paper examines multiple tuned mass dampers (TMD's) with natural frequencies distributed over a frequency range. An integral form for the impedance is developed by asymptotic techniques. The result is used to analyze the vibration control capabilities of multiple TMD's for structures subjected to wide-band input. Calculus of variations is used to optimize the design of the TMD's with a constraint on the total mass. It is found that multiple TMD's can be more effective and more robust than a single TMD with equal total mass.

Tunable vibration absorbers are used to control vibration due to time-varying harmonic disturbances. Either vibration which is local to the neutralizer, or global vibration of the host structure can be chosen as the quantity to be suppressed. In this paper, the latter is the subject of investigation

Optimum parameters of Multiple Tuned Mass Dampers (MTMD) for an undamped system to harmonic base excitation are investigated using a numerical searching technique. The criteria selected for the optimality is the minimization of steady-state displacement response of the main system. The explicit form
