Wave resistance tester for double-pole boat

Abstract

The invention provides a wave resistance tester for a double-pole boat, which comprises a supporting frame, a first test rod and a second test rod, wherein the first test rod and the second test rod are arranged on the supporting frame, and the first test rod and the second test rod can be connected with a boat model. The tester is characterized in the supporting frame is provided with a steeringdriving mechanism capable of driving the supporting rod to steer; two ends of the supporting frame are independently provided with a perforation; the first test rod and the second test rod are independently penetrated in the perforations; and the first test rod and the second test rod can vertically move in the perforations. The wave resistance tester also comprises a first displacement sensor capable of detecting the lifting and lowering amounts of the first test rod and the second test rod. By use of the structure, the dynamic operation data of the boat can be measured, the attitude data ofthe boat can be measured, and the wave resistance tester exhibits high durability. Compared with existing equipment, the wave resistance tester is greatly improved, and can be more favorably 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
