Abstract

The invention relates to a ship model near-field waveform measurement system and a measurement method thereof, including a measurement system, and its specific structure is: a support frame, a Y-direction displacement device is installed on the bottom of the support frame, and the outer surface of the support frame The Z-direction displacement device is installed on the wall, and the X-direction displacement device is installed on the outside of the Z-direction displacement device; through the cooperation of the measurement system with the ship model and the trailer, the displacements in the three directions of X, Y, and Z are changed respectively, and The data measurement and storage of the wave height meter can conveniently complete the measurement of the near-field waveform of the ship model, which is easy to operate and provides an important basis for the measurement and research of ship breaking waves.

Description

technical field [0001] The invention relates to the technical field of measurement systems, in particular to a ship model near-field waveform measurement system and a measurement method thereof. Background technique [0002] With the implementation of the Ship Energy Efficiency Design Index (EEDI) index, the demand for improving ship energy efficiency is getting higher and higher, and the optimization of the resistance performance of the ship shape line has always been the focus of ship design. Reducing the wave-making resistance is the main direction of ship type optimization, which requires the research of sailing wave-making, especially unsteady breaking waves, as a support. [0003] The precise measurement of the wave-making field of ship model navigation can provide reliable verification data for computational fluid dynamics (CFD), and at the same time support the research on the mechanism of breaking waves, and provide an effective means for the analysis and optimizati...
