The wear on main part of pump elements, such as the rotor and the valve plate, was investigated, and phase trajectories were determined based on vibration signal measured in three directions on the pump's body. In order to obtain a quantitative measure of the analyzed trajectory, the At_\{p,i\} parameter was introduced, and the relation between this parameter and the wear on the pump's parts was determined.}, type={Artykuły / Articles}, title={Application of phase trajectories to the problems of exploitation of axial piston pumps}, URL={http://www.journals.pan.pl/Content/107416/PDF/159.pdf}, doi={10.2478/v10180-010-0024-9}, keywords={axial piston pump, signal analysis, phase trajectory, machine diagnostics}, }
