The first and second sensing mechanisms 150 and 160 are slidably connected to the first and second rails 130 and 140, respectively, so that when the power unit 170 is activated, the wave glider 200 moves up and down along the arrangement direction of the first and second rails 130 and 140, simulating the motion state of the wave glider 200 in the ocean.
The operator adjusts the first and second cross bars to allow the first and second sensing mechanisms 150 and 160 to adjust the clamping distance of the wave glider 200, thereby displaying predetermined readings in the two pressure sensors 153 of the first and second sensing mechanisms 150 and 160, that is, the predetermined clamped pressure state, finally, water of a predetermined height is filled in the water tank, and the wave glider 200 and the power device 170 are started, thereby realizing the effect of simulating the activity state of the seawater, wherein the power of the wave glider 200 is turned on, causing the pressure sensor 153 in the first and second sensing mechanisms 150 and 160 to change readings, the actual value of the propulsion simulation test of the wave glider 200 can be obtained by a difference method, that is, the effect of simulating the motion state of the wave glider 200 in the sea is also realized without a large field and wave-making equipment.
