Abstract��

In view of the accelerated life testing(ALT) for the airborne hydraulic has the characteristics of long test time and many power consumption, the mechanical compensation method to save energy was brought forward based on the power recovery principle. To realize power recovery�� the flow matching condition which the test system must meet was studied. In theory, the calculating formula of the power recovery rate was derived, the influencing factors of the power recovery rate was analyzed. Through the test method, the influencing factors of the power recovery rate under the different conditions was verified, the reason for the inconsistent power recovery rate of the actual and the theoretical was also analyzed. The result indicates that the type of the power recovery method can significantly reduce the energy consumption during the ALT and has obvious energy saving effect.��
