Abstract: The technique for the on-line measurement of bulk modulus of hydraulic fluid is very important for the dynamic simulation of hydraulic systems, system monitoring and adaptive control etc. In the paper the R-C network is used to accomplish the on-line measurement of βe and the average value and fitting curve expressing the relationship of βe with pressure is proposed. Furthermore, the random error of measured results is briefly discussed.
