摘要：
The stepping of a hydraulic cylinder was analyzed based on the fluid mechanics for a control rod hydraulic drive system (CRHDS). The pressure transient was analyzed experimentally and theoretically for abnormal operating conditions. The results show that as the cylinder pressure increases, the pressure has an inflexion point when the inner cylinder reaches the top. The inner cylinder displacement increases while the speed of the inner cylinder decrease as the pressure increases. The flow velocity at the sealing ring increases due to the higher pressure between the two surfaces of the inner cylinder. This mechanism can be used to analyze the cylinder performance. © 2015, Press of Tsinghua University. All right reserved.
