Experimental Study of Hydraulic Systems Transient Response Characteristics
Abstract
The transient response characteristics of two laboratory hydraulic systems, consisting of a simple reservoir system and a pump system, were obtained both experimentally and by simulation with a computer program called 'HYTRAN'. Influence of various hydraulic components such as bends, filters and pulsation-dampening devices (Quincke-Tube) was determined by testing various experimental configurations and predicting the transient response with the 'HYTRAN' computer program. The correlation between computer and experimental results was quite good, especially in the simple reservoir system. Transient pressure peaks predicted by the computer program were within 20% of those obtained by experiment. The effect of sharp bends on system response was found to be negligible. Qunicke-Tube influence and filter influence were found to attenuate both the pump ripple and the transient pressure peak. The transient response prediction of the 'HYTRAN' program was found to be very sensitive to two input data parameters: the control valve closing time and the steady-state flow in the system.
