Floating platform pilot test motion simulation device and control method

Abstract

The invention discloses a floating platform pilot test motion simulation device, which comprises a test platform, a test body, a force application assembly, a counterweight assembly and an electric control cabinet, wherein the test platform is provided with a test groove with a hollow interior and an open top, and the test groove is provided with a plurality of transmission parts for force direction conversion; the force application assembly and the counterweight assembly are arranged on the two sides of the test tank respectively; the test body is arranged in the test groove in a floating manner through a flexible connecting piece, one end of the flexible connecting piece is connected with the counterweight assembly, and the other end of the flexible connecting piece is connected with the force application assembly; the electric control cabinet is electrically connected with the force application assembly so as to control movement of the force application assembly. The invention further discloses a control method of the floating platform pilot test motion simulation device. The pilot test motion simulation device is simple in structure and convenient to operate, can accurately and equivalently simulate the single-degree-of-freedom oscillation motion of the floating ocean platform under the actual sea condition, and can also simulate the coupling motion of multiple degrees of freedom of the platform under the inherent motion frequency of the platform.

Description

technical field [0001] The invention relates to the technical field of floating ocean platforms, in particular to a motion simulation device and control method for a pilot test of a floating platform. Background technique [0002] In recent years, as the country moves toward the deep sea, a large number of floating offshore platforms have emerged, which has become an important category of high-tech equipment for marine engineering today. The supply and demand of domestic offshore platforms has surged, and the development technology and demand for offshore oil and gas resources have continued to develop. The research and application of floating ocean platforms have received extensive and unprecedented attention. With my country's further development in the field of oil and gas resources development in the South China Sea, the demand for floating offshore platforms is becoming increasingly urgent. [0003] Floating offshore platforms will sway with different amplitudes and fr...

Problems solved by technology

[0005] The essential difference between the pilot test of the floating offshore platform and the traditional pool laboratory test is that most of the current floating platform tests are carried out indoors with small-scale non-steel material models, so there are many limitations; the pilot test usually uses large-scale steel The quality material model can be used in outdoor environments to carry out tests with a complete system configuration and a higher degree of simulation. Because its design is more in line with the needs of a specific floating offshore platform test, the required motion simulation device and control method are from the perspective of design and cost. None of the angles are suitable to mimic the laboratory pool motion simulator
