Bi-axial exciter of mechanical vibrations

This article presents mechanical vibrations exciter, which is electrohydraulic device designed to extorting bi-axial vibrations. The priority task of exciter is to excite physical model with related to exploitations real conditions parameters of signals The building of working device and his important assemblies are described. The most important part of exciter is electrohydraulic control system which ensures the obtainment of required parameters of generated signal. Exciter is compound from: mechanical construction, two servomechanisms, station of hydraulic power supply, electric power supply and control system. The possibility of built device with can extorting vibrations of horizontal platform both in one, as in two axis was introduced. For end the results after two years of exploitation were showed.
