A double-rod ship seakeeping performance tester

Abstract

The invention provides a double-rod ship seakeeping performance tester, comprising a support frame and a first test rod and a second test rod arranged on the support frame, the first test rod and the second test rod can be connected with the ship model, It is characterized in that: the support frame is provided with a steering drive mechanism capable of driving the support frame to turn, both ends of the support frame have perforations, and the first test rod and the second test rod are respectively pierced through the In the perforation, the first test rod and the second test rod can move up and down in the perforation, and a displacement sensor capable of detecting the lifting amount of the first test rod and the second test rod is also included. With this structure, it can not only measure the dynamic operation data of the ship, but also measure the attitude data of the ship, and also has high durability. Compared with the existing equipment, it has been greatly improved, and can be better applied to ship design work.

Description

technical field [0001] The invention belongs to the field of ship engineering, in particular to a double-rod ship seakeeping performance tester. Background technique [0002] The seakeeping performance tester is a device for simulating the seakeeping of ships under wave conditions. It mainly includes a support frame and a test rod arranged in the support frame. The test rod can be used to connect the ship model. When in use, connect the ship model to the test rod and place the ship model in the experimental pool, where waves are made in the experimental pool to make the ship model advance in a specific direction against the waves, and then measure the head-wave performance of the ship model in a specific direction. However, the above-mentioned device has the following defects: First, 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 thes...

Problems solved by technology

However, the above-mentioned device has the following defects: First, 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 steering, S-shaped advance, etc., for these dynamic operating conditions It is difficult to measure the seakeeping data of existing test equipment

Secondly, the existing device only has a test rod connected to the ship model, not only the connection is relatively fragile, but also the attitude data of the ship model, such as the pitch angle of the ship model, cannot be measured

In summary, the existing seakeeping data tester has the defects of incomplete test data and poor durability, which will have a certain adverse effect on ship design work
