Problems solved by technology

[0003] At present, there are mainly two types of model tests for ship models in waves, one is limited surge type, which does not reflect the real wave motion in the test, and the other is to provide ship model and measurement by stretching the springs at both ends. The force on the rod can achieve a certain degree of free surge, but the spring has elastic damping, which affects the vibration frequency and cannot reflect the real movement, which has a certain impact on the resistance measurement. control ship model

Embodiment Construction

[0038] Such as Figure 1 to Figure 3 As shown, the ship airworthiness test system of the present invention includes a pool 100, main rails 200 located on both sides of the pool, a trailer 400 located on the main rail 200, and a ship airworthiness tester 300 installed on the trailer 400. The trailer 400 is used to tow the ship seaworthiness tester 300 to move along the main track 200 .

[0039] During the test, the ship model 10 is connected under the ship seaworthiness tester 300 , dragged by the trailer 400 , and the ship model 10 is driven by the ship seaworthiness tester 300 to sail on the simulated water surface 101 with waves in the pool 100 .

[0040] In order to adjust the position of the ship seaworthiness tester 300 on the trailer 400 conveniently, so as to adapt to connecting different types of ship models, the trailer 400 also has a trailer track 401 . After the ship seaworthiness tester 300 is adjusted on the trailer track 401 , it is locked with the locking mecha...

Abstract

The invention discloses a ship seaworthiness performance testing system, which includes a ship seaworthiness tester set on a pool and capable of being dragged by a trailer, the ship seaworthiness tester includes a pair of column frames, and is arranged between the pair of column frames The beam frame, and the airworthiness test device and the following brake device located on the beam frame. The airworthiness test device uses the linear motor of the magnetic levitation principle as the control and measurement method, and under the condition of ultra-low damping, it measures the movement attitude and resistance increase of the ship model in waves under the condition of no other constraints except yaw and sway Happening. The following brake device utilizes the following principle of the linear motor, converts the movement of the pneumatic cylinder into mechanical clamping, and clamps and releases the track through the track clamp to achieve the start-stop control of the ship model in the waves. The invention realizes accurate measurement of the navigable state of the ship model in simulated waves.

Description

technical field [0001] The invention belongs to the technical field of ship testing, and in particular relates to a system for testing the heave, pitch, resistance, surge and roll of a ship model in waves to test the seaworthiness of the ship. Background technique [0002] With the continuous development and innovation of shipping technology, improving the accuracy of ship performance prediction is an important means of ship type development, and the accuracy of model tests directly affects the accuracy of ship performance prediction. Such testing techniques directly affect the accuracy of model tests and are an important basis for ship performance prediction. [0003] At present, there are mainly two types of model tests for ship models in waves, one is limited surge type, which does not reflect the real wave motion in the test, and the other is to provide ship model and measurement by stretching the springs at both ends. The force on the rod can achieve a certain degree o...
