Abstract
This paper presents a stochastic approach for the optimum design of a single tuned
mass damper (TMD) protecting a linear mechanical system. The optimum strategy is
directed towards maximizing the effectiveness of the TMD in reducing the vibration
level in the system to be protected. This performance is evaluated on the basis of the
reduction of the root-mean-square displacement and acceleration of the main system.
Several numerical analyses are carried out for assessing the influence of the system
and the excitation characteristics of the optimum TMD. In particular, a comparison
between the TMD optimum designs for a system excited by stationary and nonstationary
filtered white noise is presented. Finally, the advantages of modelling the
seismic excitation as non-stationary filtered white noise for the optimum TMD
design are clearly stated.
