Abstract

Aiming at remote pressure-regulating system and based on dynamic-characteristics fundamental equation of distributed-parameter model in hydraulic pipelines, the mathematical model of remote pressure-regulating hydraulic pipelines is deduced. The condition of resonance in hydraulic pipeline is discussed under the condition of controllable maximum stiffness coefficient. The results show that, the controllability of a remote pressure-regulating system depends on the length of remote pressure-regulating pipeline to a certain extent. Thus two conditions must be derived if a remote pressure-regulating system wants to work normally, one is under the conditions of controllable maximum stiffness coefficient and the other is a suitable length of remote pressure-regulating pipeline to avoid resonance.
