Abstract

The invention relates to a digital novel relative ship wave speed measuring device. The digital novel relative ship wave speed measuring device comprises a high-precision signal module, wherein the high-precision signal module are connected with a dynamic data acquisition instrument and a power supply through communication cables respectively; a capacitive sensor is mounted on the high-precision signal module; the capacitive positive electrode of the capacitive sensor is a tantalum wire, and the negative electrode thereof is a copper wire; one end of the tantalum wire is connected to the high-precision signal module and is fixed by fitting the side surface of a ship hull; the other end of the tantalum wire is fixed to the bottom surface of the ship hull; one end of the copper wire is connected to the high-precision signal module; the other end of the copper wire stretches into water where the ship hull is positioned; the dynamic data acquisition instrument transmits data acquired fromthe high-precision signal module to a computer. The digital novel relative ship wave speed measuring device is simple in structure and convenient to operate, can quickly and accurately measure the relative motional speed of a ship wave and provides an accurate and effective data support for research and calculation of a slamming load.

Description

technical field [0001] The invention relates to the technical field of ship model wave load testing and testing, in particular to a new digital ship wave relative velocity measuring device for measuring the relative movement displacement and velocity of the ship hull model. Background technique [0002] When a ship sails in waves, it will bear continuous force from waves, especially in extreme environments where the load presents strong nonlinear characteristics, such as hull slamming and rising waves. Severe slamming, on the one hand, makes the impact area bear huge pressure, and the local structure may be damaged; May result in loss of overall longitudinal strength of the hull. Therefore, the research on the hull slamming load is of great significance to the structural dynamic response of the hull, whether it is the local strength problem or the overall strength problem. [0003] Many relevant international scholars have carried out numerical calculation and model test r...
