Drive with Hook´s joints is a transverse oscillating evolutive system. The spectrum of natural frequencies of relative transverse bending vibration quite considerably depends on the operating parameter of a drive, i. e. on the angular velocity of propshaft system rotation. As a result of angular velocity increasing, the values of relative vibration natural frequencies decrease. In some particular cases, the decrease is about 50 %. This fact is especially dangerous in cases of drives whose shafts speeds are during operation in the area just below the critical speeds. Then, it´s necessary to deal not only with the question of the speed resonance position, but also analyzing the dynamic deformation and other state variables in the individual sections of a shaft. The transfer-matrix method can be used also in case of rotating parts of gear pumps whose shafts make flexural oscillation during the rotation.
