Temporary test pool false bottom unit and seakeeping test method based on same

Abstract

The invention belongs to the technical field of deepwater test pools, and particularly relates to a temporary test pool false bottom unit and a seakeeping test method based on the temporary test pool false bottom unit. The temporary test pool false bottom is provided for a test pool without a permanent steel structure pool false bottom, the temporary test pool false bottom adopts a detachable unit structure design, can be directly assembled according to use requirements during use, can be disassembled and placed after being fished after a test is finished, and is convenient to use. In addition, the water depth height can meet the use requirement by adjusting the length of the steel cable, and the seabed conditions under various water depths can be simulated. Meanwhile, the temporary test pool false bottom provides a seabed anchoring point for the anchor chain, the bottom laying effect of the anchor chain is achieved, the offshore inclined seabed and the marine environment of the complex seabed landform can be simulated, the marine environment of a real ship during working is closely simulated, and test data are more reliable.

Description

technical field [0001] The invention belongs to the technical field of deep water test pool tests, and in particular relates to a false bottom unit of a temporary test pool and a seakeeping test method based on the device. Background technique [0002] As the country vigorously develops the marine industry, various marine equipment is constantly being introduced, and model testing is the most accurate and common method for predicting the performance of marine equipment. The deep-water test tank is one of the most important test equipment for model tests. In order to simulate the marine environment of different water depths, the deep-water test tank is usually equipped with a large false bottom of the pool, and the depth of the water in different marine environments can be simulated by adjusting the height of the false bottom. [0003] As an important part of the ocean engineering pool, the false bottom of the pool is mainly used to simulate the seabed plane and simulate the ...

AI Technical Summary

Problems solved by technology

Generally, the liftable false bottom is composed of steel structure, and its structural composition and installation conditions are relatively complicated.

As a large-scale steel structure, the false bottom is expensive, heavy, and heavy on the structure. The equipment is often out of operation and requires frequent maintenance.

In addition, some domestic deep-water test pools do not have steel structure false bottoms, so model tests under mooring conditions cannot be carried out.
