To provide a shaking system capable of compensation for influence of the reaction force of a test sample without requiring addition of an element leading to upsizing of the system and, further, capable of real-time compensation for the reaction force of the test sample in the direction of the rotation in the above compensation case.
In a shaking system comprising a table 2 and a hydraulic shaker wherein a test sample 4 held on the table is vibrated by the hydraulic shaker through the table: a load added to the hydraulic shaker from the table is calculated in a load calculation part 23a; a compensation signal 113a for compensating for the load is generated in a signal calculation part 24a; and the compensation signal is added to a servo signal 105a and it is outputted to a servo valve 14a for controlling the hydraulic shaker.
