Experimental measurement device and method of catamaran torque

Abstract

The invention discloses an experimental measuring device for torque of a catamaran. The catamaran is composed of a first hull, a second hull and a connecting bridge. The first hull is located in a first water tank, and the first water tank is divided into a first The water tank unit and the second water tank unit, the first water tank unit and the second water tank unit are respectively provided with a first circulation device and a second circulation device, the second hull is located in the second water tank, and the second water tank is divided into a third water tank The unit and the fourth water tank unit, the third water tank unit and the fourth water tank unit are respectively provided with a third circulation device and a fourth circulation device. The present invention uses the volume of water in four independent loading water tanks to simulate that the bow of one sheet body is at the wave trough and the stern is at the wave peak; Simulate different wave heights, thereby simulating the torque on the catamaran, making the experiment real, easy to observe, and convincing.

Description

technical field [0001] The invention relates to an experimental measuring device and a measuring method for the torque of a catamaran, and belongs to the field of catamarans. Background technique [0002] At present, the research on catamaran torque mainly focuses on external load calculation, finite element numerical simulation or ship model wave load experiment in the towing tank. 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, coupled with the relatively high cost of the test, there are certain limitations in the teaching process, so it is not suitable for demonstrations to students during the teaching process. Due to the above objective factors...

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
