To explore the main characteristics and energy conversion mechanism of rotational inertia hydraulic converter (RIHC). Using a rotating inertia hydraulic converter configuration powered by an analogous rapid switching valve, the overall theoretical model was developed to investigate the key features and energy conversion mechanism of the device. The results indicated that the main characteristics can be basically predicted by the theoretical model, and the rotational inertia can be effectively quantified by the suction flow rate, whose mean value reach to the peak value at the duty cycle of 0.5. In the effective duty cycle control mode of PWM signal, with the growth of the flywheel rotation speed and load pressure, the positively correlated throttling power loss and system efficiency are acquired. When the load pressure is between 0 and 4 MPa, experimental comparison showed that the RIHC may reduce throttling power loss by up to 89% and achieve an increase in system efficiency of 15.7% while compared to CPHS.
