Abstract: A general expression for the power flow transmitted to a
flexible seating via spring-like mounts from a rigid body
excited by a harmonic off-centre force is developed. By
calculating and analyzing the power flow frequency spectrum of a
numerical example, some important influences offcentre force
excitation on the power transmission as well as on the
vibration isolation efficiency of asymmetrical flexible systems
are demonstrated substantially.
Key words: Power
