Floating Gate Model Testing Device with Multi-Degree-of-Freedom Guide Mechanism

The patent transforms the conventional static towing tank environment into a dynamic testing system. The model is given multiple degrees of freedom to move actively (heave, pitch, roll, surge) while the water remains stationary. This dynamic approach allows the model to experience current-like conditions from various angles without requiring the water to actually flow, thereby achieving versatility in hydrodynamic measurement without the complexity of multiple water flow systems.

Instead of moving the water to create currents of various angles (conventional approach), the patent inverts the approach by keeping the water stationary and moving the model in multiple degrees of freedom. This inversion achieves the same measurement capability while avoiding the complexity of generating flowing water with various angles in the towing tank.

The model support system transitions from a fixed constraint to a dynamic multi-degree-of-freedom system. The model can move in heave, pitch, roll, and surge while being guided by mechanisms that maintain measurement accuracy. This dynamic capability allows the model to simulate responses to currents from various angles without requiring complex external flow generation systems.

The testing device achieves multi-functionality by enabling the model to experience hydrodynamic conditions equivalent to various current angles through its multi-degree-of-freedom movement capability. A single stationary water environment can thus serve multiple testing purposes that would traditionally require multiple flow configurations or separate testing systems.
