摘要

The application of passive and adaptive-passive (also known as semi-active) vibration absorbers in hydraulic systems has been investigated for the case of a linear frequency rise of the excitation. The investigation is based on a simulation model consisting of a main hydraulic system, modelled as an ideal flow source (mean flow and one harmonic), a hydraulic line and a sharp edged orifice. The vibration absorber was modelled as a constant mass m, a stiffness c (constant or either continuously or discretely variable in value) and a damping d.
