The present invention relates to the wave energy test technology field, especially to a flexible tube component wave energy test device capable of verifying wave energy through adoption of a flexible tube component and a test method thereof. The device comprises a water tank filled with water, a piston module, a power module and a flexible tube component, the flexible tube component is connected with the outlet of the water tank. Under the action of the piston module and the power module in the water tank, stable and continuous regular excitation surges with different periods are generated in the flexible tube component connected with the outlet to reach the test purpose.
