<P>PROBLEM TO BE SOLVED: To provide a damping test method, a control apparatus, a hydraulic system and a program capable of improving reliability of a damping test result without using a pressure sensor. <P>SOLUTION: The hydraulic system 30 includes actuators 11 and 12, and the control apparatus 40. The control apparatus 40 acquires an ideal velocity characteristic of a control surface and the temperature of pressure oil of the actuators 11 and 12 to be tested and operating speed of the control surface when the actuators 11 and 12 are attached to the control surface. The control apparatus 40 corrects the ideal velocity characteristic of the control surface by using the acquired pressure oil temperature and control surface operating speed. The control apparatus 40 sets an upper limit and a lower limit by using a predicted value for a fluctuation range for a fluctuation factor that causes a fluctuation of the control surface operating speed, with reference to the corrected ideal velocity characteristic, measures the pressure oil temperature and the operating speed by actuating the control surfaces, with the actuator to be tested placed in a damping mode, and determines whether the measured value falls within the range between the upper limit and the lower limit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
