N2 - This paper investigates the force and power transmission behaviour between a bilinear oscillator and a linear oscillator. Both harmonic balance method and numerical integrations are used to examine the steady-state force transmissibility and time-averaged power flow variables. It is found that a larger bilinear stiffness ratio may an effective mitigation in force and power transmission in low-frequency range. It is shown that a larger bilinear stiffness ratio also could shift the first resonant peak of response curves to high frequencies. It is also found that the portion of time-averaged input power, which is transmitted from bilinear oscillator through linear interface to linear oscillator, keeps almost the same despite of variations of bilinear stiffness.
