摘要：
The paper presents theoretical modeling and an experimental investigation of the variation of oil effective bulk modulus (beta(e)) with pressure in hydraulic systems. A pressure sensitive model Of beta(e) and its several simplified forms have been derived. In addition, a method for parameter identification has been formulated. In an actual hydraulic systems, values for beta(e) at different load pressures were obtained, model parameters identified and modelling errors evaluated.
