Hydrodynamics Research and Progress Series A, 2007, 022(002); ISSN: 1000-4874) By establishing a three-dimensional numerical pool, the numerical simulation of the waves on the deck of a fixed FPSO under regular waves is carried out, and the deck and deckhouse are obtained. The impact load and the height of the water level on the deck of the wave and the process of the wave climbing, deformation, and breaking along the bow, but it has not passed a set of test devices for model tests
Moreover, in the prior art, it is not very convenient to clearly observe the whole surfing process due to the problems of the materials and layout of the test device; it is also difficult to test the impact load, and often only the pressure value at certain points can be tested. The impact force generated by the whole sea load cannot be tested

Embodiment Construction

[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 , figure 2 As shown, the present invention has an upper panel 1 and a lower panel 2, and a rear baffle 4 vertically connected to the upper panel 1 and the lower panel 2, and the front baffle 3 is connected to the rear baffle 4 through a load cell 7, and the connection method It adopts a plate-type double-hole beam structure.

[0018] Such as figure 1 As shown, multiple groups of steel wire rods 5 and tantalum wires 6 are connected between the upper panel 1 and the lower panel 2 . The function of the steel wire rod 5 is to ensure the strength and stability of the support, while the wire rod 5 also has the function of grounding. The tantalum wire 6 is the wave surface height testing unit, which is perpendicular to the upper panel 1 and the lower panel 2 . figure 2 The location of distribution points of the wavefr...

Abstract

The invention relates to a testing device for a wave surface height and an impact load, which is provided with an upper panel, a lower panel, a rear baffle and a front baffle. The rear baffle is vertically connected with the upper panel and the lower panel, the front baffle is connected with the rear baffle by a force-testing element, and a plurality of steel wire rods and tantalum wires are connected between the upper panel and the lower panel. The testing device for a wave surface height and an impact load is used for measuring the wave surface motion condition and the impact load quantity of green water on a bow deck and can provide a reliable measuring method for testing and researching green water in a model test.

Description

technical field [0001] The invention belongs to the field of overall performance testing of ships, and in particular relates to a device for testing wave surface height and impact load. Background technique [0002] The model test research work on deck waves has important engineering significance. A large number of experimental work revolves around the qualitative or quantitative analysis of different parameters on the occurrence probability of waves, the movement of the hull in waves, the flow of water on the deck, impact loads, etc. developed under the influence of issues of concern in the [0003] At home and abroad, there are researches on testing technology based on PIV (Particle Imaging Velocimetry) and wave height meter. The document "2D Numerical Simulation and Experimental Research of Waves on Deck" (Zhang Zhaogang, Zhu Renqing, Miao Quanming, etc.). 2D Numerical Simulation and Experimental Research of Waves on Deck. Nautical Engineering, 2008, 037 (002), ISSN: 167...
