000022707 520__ $$2eng$$aVibration is a common phenomenon in mechanical systems. But it can have many adverse effects on the functioning and durability of mechanisms. Particularly dangerous is resonance, i.e. the superimposition of the excitation frequency on the free vibration frequency of an element. Both flexible and rigid tubes belong to the hydrostatic drive's elements most susceptible to resonance. In their case, excitations most often originate from fluctuations in working fluid pressure and also from the vibrations of the other elements of a machine incorporating a hydraulic system. One of the ways of avoiding resonance is to design such geometry and fixing of the components that their free vibration frequencies do not coincide with the excitation. This paper presents an experimental approach to determining proper frequencies. An appropriate test stand and the way of conducting the experiment are described and analyses of the measured data are carried out. Moreover, the effect of the pressure and rate of flow of the fluid in the hose on the fundamental frequency of transverse vibrations is examined.
