Problems solved by technology

However, the above-mentioned device has the following defects: the existing device can only measure the seakeeping data of the ship model in a specific orientation, while the actual ship operation is dynamic, such as turning, S-shaped advance, etc., for the seakeeping data under these dynamic operating conditions data, which is difficult to measure with existing test setups
The lack of these key test data may have a certain adverse effect on the ship design work

Embodiment Construction

[0027] The present invention is further elaborated below by specific embodiment:

[0028] Such as figure 1 As shown, the all-wave ship seakeeping performance tester of the present invention includes a support frame 100 , a test rod 200 , a gantry frame 300 , a steering drive mechanism 400 , a counterweight 500 and a connecting frame 600 .

[0029] Wherein, the support frame 100 is composed of two I-beams 101 arranged in parallel, an intermediate support plate 102 connected across the middle of the upper surface of the two I-beams 101, and respectively straddling and connected to the upper and lower ends of the two I-beams. The end upper support plate 103 and the end lower support plate 104 of the surface are formed. The middle positions of the upper support plate 103 at the end and the lower support plate 104 have perforations 105 aligned up and down.

[0030] The test rod 200 is composed of a long rod 201 , a three-component force sensor 202 and a ship model connector 203 w...

Abstract

The invention provides a full-wave-direction ship sea keeping performance tester. The full-wave-direction ship sea keeping performance tester comprises a supporting frame, a connecting frame, and a test rod arranged on the supporting frame, wherein the test rod is provided with a three-component-force sensor and a ship model connector capable of being connected to a ship model. The full-wave-direction ship sea keeping performance tester is characterized in that: a steering driving mechanism capable of driving the supporting frame to steer is arranged between the supporting frame and the connecting frame. By adopting the structure, a head sea angle of the ship model can be changed at any time and any place during the test to simulate the dynamic operation of a ship, so as to obtain more andmore comprehensive test data of the sea keeping performance of the ship model, so that the ship design work is performed more efficiently.

Description

technical field [0001] The invention belongs to the field of ship engineering, and in particular relates to a tester for seakeeping performance of ships in all waves. Background technique [0002] The seakeeping performance tester is a device for simulating the seakeeping of ships under wave conditions, which mainly includes an experimental pool, a ship model and a pendulum for placing the ship model. When in use, waves are created in the experimental pool, so that the ship model moves forward in a specific direction, and then the head-wave performance of the ship model in a specific direction is measured. However, the above-mentioned device has the following defects: the existing device can only measure the seakeeping data of the ship model in a specific orientation, while the actual ship operation is dynamic, such as turning, S-shaped advance, etc., for the seakeeping data under these dynamic operating conditions data, it is difficult to measure it with existing test equi...
