[0002] A ship is a structure that can carry cargo and has power. Its shape is often designed differently due to the weather of the route, the type of cargo, the amount of cargo and the speed of navigation. The design of the ship is based on certain assumptions and referring to the same Therefore, the performance of the built ship may not fully meet the expectations in the design stage. If the performance of the ship cannot be fully understood before construction, it will be discovered that the required speed or speed cannot be reached after the construction is completed. The speed of the propeller cannot be turned up. Even if this defect can be improved technically, it is not easy to make up for the ideal level, and it will cause waste of time and economy.

Therefore, model experiments are used to estimate the hydrodynamic performance of ships such as resistance and propulsion to assist ship design. The so-called ship model experiment is to make a ship model according to a certain scale ratio, and conduct tests on the ship to study the ship performance. However, the existing The ship model experiment measurement equipment has a single function and can only perform a single experiment, it is difficult to conduct multiple experiments and receive experimental data in different environments, and cannot meet the requirements of different measurement environments
