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 seagoing capability testing system. The ship seagoing capability testing system comprises a ship seagoing capability tester which is arranged on a water pond and can be dragged by a trailer, wherein the ship seagoing capability tester comprises a pair of stand column racks, a crossbeam rack which is arranged between the pair of stand column racks, and a seagoing capability testing device and a follow-up braking device which are located on the crossbeam rack. The seagoing capability testing device uses a linear motor in a magnetic levitation principle as a control and measurement means to measure a motion attitude and a resistance increase situation of a ship model in waves under no constraint conditions except yawing and swaying under a situation of ultralow damping. The follow-up braking device uses the follow-up principle of the linear motor, converts motion into mechanical clamping through a pneumatic cylinder and realizes starting and stopping control of the ship model in waves by clamping and releasing a track through a track clamp. The ship seagoing capability testing system realizes the accurate measurement of the seagoing capability 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...
