Wave gliders are one of the typical representatives, consisting of three parts, a surface float, an underwater tractor, and an umbilical cable connecting the two. The water surface floating body provides buoyancy and provides energy for communication, control and data acquisition by installing a solar panel; the wing plates of the underwater traction machine are vertically excited by the up-and-down fluctuation of waves to swing up and down so as to generate forward driving force.
At present, the research on the propelling performance of the underwater tractor part of the wave glider mainly depends on a water pool or a water tank to carry out the test. The test is required to be carried out in a water tank or a water tank meeting the scale requirements of the simulation test, and each test is required to be completed by installing all components such as a wing plate, a spring and the like of the underwater tractor and repeatedly debugging, and meanwhile, a matched wave environment simulation device is required for simulating the wave environment and the motion state of the underwater tractor. Therefore, the wave glider has the advantages of various devices and complex structure required by the complete simulation test; meanwhile, the requirement on the site scale is very high, and the manufacturing cost is high; when the propulsion performance of the swing wing plate of the wave energy propulsion unmanned ship is researched by the existing test equipment, a complete underwater propulsion mechanism needs to be researched, wherein the number of the wing plate, the spring and other parts is numerous, the installation is complex and time-consuming, and meanwhile, the requirements on the field scale and the installation of the measuring equipment are very high, the test steps are complex, the efficiency is low, and the manufacturing cost is high.
