Frequently asked questions

Q1. What have the authors contributed in "Optimal design of a novel tuned mass-damper-inerter (tmdi) passive vibration control configuration for stochastically support-excited structural systems" ?

This paper proposes a novel passive vibration control configuration, namely the tuned massdamper-inerter ( TMDI ), introduced as a generalization of the classical tuned mass-damper ( TMD ), to suppress the oscillatory motion of stochastically support excited mechanical cascaded ( chain-like ) systems. Furthermore, pertinent numerical data are furnished, derived by means of a numerical optimization procedure, for a 3-DOF classically damped primary structure base excited by stationary colored noise, which exemplify the effectiveness of the TMDI over the classical TMD to suppress the fundamental mode of vibration for MDOF structures.
