Background
It is known that ships or marine structures face a great deal of danger when sailing offshore, or sailing, the most critical of which is the impact of wind and waves. In order to prepare for the risk without serious consequences, the vessel or marine structure is subjected to wave endurance tests during design. Sea-surfing resistance refers to the performance of a ship, etc., which has enough stability and structural strength of a ship body when the ship, etc., generates swaying motion, slamming, surging, stalling, etc., under the action of external force such as wind wave, etc., and can keep a certain navigational speed and safe navigation.
The wave endurance test mainly simulates six-freedom-degree force of the ship in waves, including pitching, rolling, yawing, pitching, yawing and heaving, by performing an upward wave simulation test on a ship model ship or an ocean structure model. The motions of three degrees of freedom most concerned in the wave resistance are roll, pitch, and heave. In the existing ship and ocean structure model test, the contact type measurement of the multi-degree-of-freedom motion response is completed by means of an airworthiness instrument.
However, the existing airworthiness instrument has the advantages of large volume, heavy weight, high cost, strict maintenance requirement, strong constraint effect on a test model in use, and incapability of intuitively reflecting the real motion attitude of the test model.
