Vibration transmission and power flow in impact oscillators with linear and nonlinear constraints

This paper investigates the vibration transmission and power flow behaviour of impact oscillators comprising linear or quasi-zero-stiffness (QZS) nonlinear constraints. The steady-state responses of the systems subjected to a harmonic excitation are obtained by the harmonic balance (HB) approximations and numerical integrations. The level of vibration transmission within the systems is quantified by the force transmissibility and time-averaged...
