The performance of hydraulic system employing counterbalance valves frequently encounter problem due to oscillation which are primarily due to the load inertia, volume of pressure system, response of the counterbalance valve and the flow at which the valve is required to regulate the load. This paper describes an application of CAD via a computer simulation analysis in the design of a hydraulic system employing counterbalance valve. The computer simulation results are compared with those obtained from steady state and transient experimental tests. The analysis shows the advantages of CAD in the design of the hydraulic system, especially to predict the performance of the system for all range of operational conditions. |
