Description

TECHNICAL FIELD

[0001] The utility model relates to a surge simulation device technical field, concretely is a model surge navigation simulation device for ship design. BACKGROUND

[0002] Sea surge, also known as swell, is a series of mechanical waves or surface gravity waves that accumulate after traveling thousands of miles in the ocean. When the wind force decreases rapidly and subsides, the wave is left behind. When designing a ship, a small-scale model needs to be made. After the model is completed, it can be tested for navigation. Through navigation testing, the deficiencies in ship design can be directly observed, so that designers can research and address the deficiencies. Surge testing is an important testing step when testing a ship model. Traditional testing methods are mostly one-way surge testing. During the testing process, the ship model needs to be adjusted and tested multiple times to measure the accurate simulation data of each position of the ship. The testing efficiency is low. To improve this situation, a model surge navigation simulation device for ship design is proposed.

[0003] A novel model surge navigation simulation device for ship design is disclosed in the authorized announcement No. CN222421155U, which comprises a simulation frame, a rotating seat and a guide seat. The bottom end outside of the simulation frame is connected with a bearing frame. The bearing frame is L-shaped, which allows the operation lever and the linkage rod to rotate without obstruction. The bottom end surface of the simulation frame is provided with a direction scale. The rotating seat is connected to the center of the bottom end of the simulation frame. The outer side of the rotating seat is connected with a linkage rod. The inner side of the bottom end of the simulation frame is fixedly connected with a guide ring.

[0004] When the simulation device is used, the operation lever is pushed upwards, and the spline shaft enters the spline groove from the circular groove. At this time, the rotating operation lever can rotate the rotating seat. The guide sleeve moves along the guide ring to change the direction of the surge generated by the stirring frame. The angle can be accurately controlled by the indication frame and the direction scale.
