The paper describes results of several years of authors investigations of the dynamic properties of hydrostatic elements and assemblies based upon simultanious usage of digital simulations techniques and experimantal measurements. A hydrostatic system has been built and tested phisically, as well as it's simulation model hs been prepared and investegated. 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 an phisical experiments the hydrostatic system was subject to excitations of Pseudo-Random Binary Signal (PRBS) type. Comparisons of the results of both approaches show good agreement
