摘要
The presence of air bubbles in hydraulic fluid changes very strongly the fluid compressibility which gives rise to a negative fact in the system behavior. This paper discusses the problem of interest and gives some instructions to determine the critical volume ratio of air-oil mixture from the point of view of both transient response and steady-state of the system. The suitable operation pressure is also proposed for a required system behavior.
