The paper describes results of several years of authors investigations of the dynamic properties of hydrostatic elements and assemblies based upon simultaneous usage of digital simulations techniques and experimental measurements. A hydrostatic system has been built and tested physically, as well as it's simulation model has been prepared and investigated. Simulation has been performed with the aid the POLSYAS system, described elsewhere, which is based upon the bond-graph dynamic system description and performs automatic generation of the state equations. In both: numerical and physical experiments the hydrostatic system was subject to excitations of the Pseudo-Random Binary Signal /PRBS/ type. Comparisons of the results of both approaches show good agreement.
