The invention relates to the technical field of water tunnel experiments, in particular to a towing tank test bed convenient to disassemble and assemble.
Background
The water tunnel is a very effective experimental device for hydrodynamic experimental research, and is mainly used for researching the interaction force between an experimental object and water flow. In the water tunnel system, the pressure and the flow rate are respectively controllable, and the water can be recycled. The cross section of the water tunnel experiment section also has different shapes, such as square, rectangle and round, and the like, so that the data can be observed at multiple angles to complete recording scientific research or test work.
In order to carry out hydrodynamic experiments, an expected relative movement speed between an experimental object and fluid must be achieved, water holes can be divided into two categories according to the difference of the motion states of the experimental object and the fluid, the first category of experimental object keeps the flow direction relatively static, and a fluid medium is in a flowing state, and the water holes comprise a circulating water hole, a gravity type water hole and the like; in the second type of water tunnel design, a fluid medium is in a static state, and an experimental object is in a moving state, and the water tunnel comprises a towing tank, a swing arm tank and the like. The gravity type water tunnel is the water tunnel powered by gravity, a power system does not need to be additionally arranged, and the water flow speed is often low.
The towing tank is another hydrodynamic experimental device, and the experimental object in the experiment is towed by an electric trailer, so that the towing tank is named. In 1872 the first model test pool in the world was created by the uk shipbuilding chemist w. In 1954, China built a first water pool in Shanghai, which is 70m long, 5m wide and 2.5m deep in water. The towing tank of the Xuhui school district of Shanghai traffic university is built in 1958, and is the earliest built double-track ship model towing tank in new China. The length of the towing tank is 110m, the width is 6.0m, the water depth is 3.0m, and the maximum towing speed of the trailer can reach 6.0 m/s. The China center for Ship science research built a large-scale water pool with no tin in 1965, the length of the water pool is 474 meters, the water depth is 7 meters, and the width of the pool in a test section is 14 meters. 9 months 2014, the university of nan-compton, uk completed the construction of a novel towing tank, the dimensions of the tank were 138m, 6m and 3.5m in length and width respectively, and the maximum towing speed was 12 m/s. At present, a built multifunctional towing tank in Min-scholar school district of Shanghai traffic university has the length of 300m, the width of the tank of 16m and the depth of 7.5m, and the maximum towing speed reaches 10 m/s.
The towing tank is designed and constructed to meet the requirements of large-scale experimental objects such as ships, submarines and the like, the construction cost is high, and the construction is difficult to support by general colleges and research institutions. However, a significant portion of the hydrodynamic experimental requirements are smaller subjects and require lower flow rates. Therefore, it is necessary to develop low-cost hydrokinetic experimental equipment to meet this part of experimental requirements.
