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 transverse waves, and lacks economical and intuitive teaching and experimental equipment for students to operate by themselves so as to gain a deep understanding

Abstract

The invention discloses an experimental device for measuring a transverse moment of a catamaran. The catamaran is composed of a first ship body, a second ship body and a connection bridge, wherein the first ship body is located in a first loading glass water tank; the first loading glass water tank is connected with a first circulating water pipe; a first circulating pump is arranged on the first circulating water pipe; two ports where the first circulating water pipe and the first loading glass water tank are connected are provided with first steady flow glass water tanks respectively; the first loading glass water tank is internally provided with a first water velocity meter; a strain gauge is attached to the part where the transverse bulkhead on the first ship body and the connection bridge are contacted; the strain gauge is connected with a charge amplifier via a wire; and the charge amplifier is sequentially connected with a multichannel information collector and a computer. As the experimental device in teaching, due to different water volumes in loading water tanks, simulation sheet bodies are respectively located in a wave crest and a wave trough.

Description

technical field [0001] The invention relates to an experimental device and an experimental method for measuring the lateral bending moment 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 s...
