Eigenfrequency of hydraulic systems belongs to important dynamic quantities. If the excitation frequency of a given hydraulic system is equal to the system eigenfrequency, high-amplitude pressure and flow pulsations can arise. It has a negative influence on load of hydraulic elements, system tightness etc. For this reason it is necessary to eliminate the operation of the hydraulic system at its eigenfrequency. The paper deals with experimental determination of the system eigenfrequency in various operating modes of the investigated loading device.
