Experimental device for measuring torque of catamaran and experimental method

Abstract

The invention discloses an experimental device for measuring the torque of a catamaran. The catamaran is composed of a first hull, a second hull and a connection bridge, wherein the connection bridge is connected with the first hull and the second hull, the first hull and the second hull are respectively located in four independent water tanks, the water tanks are internally provided with water circulating devices, and the water tanks are further internally provided with speed measuring instruments used for measuring the circulating water; a strain gauge is installed at the position where the transverse bulkhead of the first ship body is contacted with the connection bridge, the strain gauge is connected with a charge amplifier through a wire, the charge amplifier is sequentially connected with a multichannel information acquisition instrument and a computer. The experimental device simulates that the stem part of one hull is located at a wave trough and the stern part is located at the wave crest and that the stem part of the other hull is located at the crest peak and the stern part is located at the wave trough through the volume of water in the four independent loading water tanks, and different wave heights can be simulated through controlling the relative height, thereby simulating the torque received by the catamaran, and enabling the experiment to be real, easy to observe and persuasive.

Description

technical field [0001] The invention relates to an experimental device and an experimental method for measuring the torque of a catamaran, and belongs to the field of measuring the catamaran. Background technique [0002] Since the beginning of the new century, due to the in-depth development of economic globalization, economic and trade exchanges between countries in the world have become more and more frequent. With the continuous expansion of the world's shipping market and the increasingly prominent environmental issues that people care about in recent years, these have prompted people to develop new, high-performance ship types to replace existing ship types. As an important ship type, the catamaran has attracted more and more attention because of its unique advantages. Due to the large lateral width between the two hulls of the catamaran, it has a larger molded width than the general monohull, resulting in a smaller length-to-width ratio of the whole ship, so the prob...

Problems solved by technology

The first two are basically based on theoretical calculations, and students cannot conduct intuitive observation and actual hands-on operations during the teaching process, which has certain defects in deepening the learning impression; the latter requires certain experimental conditions, and the current construction in colleges and universities There are not many towed pools, and the test cost is relatively high, so there are certain limitations in the teaching process, so it is not suitable to demonstrate to students during the teaching process

Due to the above objective factors, the current teaching process only lists the discussion of the external force of the catamaran in the state of oblique waves, and lacks economical and intuitive teaching and experimental equipment for students to operate by themselves so as to gain a deep understanding
