Experimental platform for simulating ocean platform motion compensation and experimental method thereof

Abstract

The invention provides an experimental platform for simulating ocean platform motion compensation and an experimental method thereof. The experimental platform is characterized by comprising a motion simulation platform, a motion compensation platform on the motion simulation platform, and a data acquisition processing and control device, wherein the motion simulation platform is a six-degrees-of-freedom parallel mechanism, the motion compensation platform is a three-degrees-of-freedom parallel mechanism, and the data acquisition processing and control device includes an attitude sensor arranged on the motion simulation platform, a PAC and a computer. The motion simulation platform is preferably a 6-SPS Stewart parallel mechanism or a 6-UPS Stewart parallel mechanism. The motion compensation platform is preferably a 3-SPS parallel mechanism, a 3-UPU parallel mechanism or a 3-RPS parallel mechanism. The experimental cost can be reduced, and the hidden danger of experiment on an ocean platform or ship can be eliminated. The experimental method of the invention is simple, easy to operate, and efficient.

Description

technical field [0001] The invention belongs to the technical field of floating ocean platforms, and relates to an experiment platform for the ocean platform, in particular to an experiment platform and an experiment method for simulating motion compensation of the ocean platform. Background technique [0002] With the development of the economy, land resources are gradually in short supply, and the focus of development is gradually shifting from land to sea. The complex environment in the ocean has a great impact on the work and production at sea, especially under the wave load, the ocean platform or ship will produce complex movements with six degrees of freedom, which has brought great impact on the equipment and personnel on the platform. potential safety hazards, such as the impact of sloshing on offshore hoisting, the impact of sloshing of scientific research vessels on on-board instruments, and the impact of relative movement between platforms on the transfer of perso...

AI Technical Summary

Problems solved by technology

The application of this type of motion compensation device is inseparable from a large number of experimental simulations in the early stage. Due to the high cost and potential safety hazards of experiments on offshore platforms or ships, it is urgent to design a device that can be used under laboratory conditions. The experimental platform for simulating the motion compensation of the offshore platform can reduce the cost of the experiment and eliminate the safety hazards of conducting experiments on the offshore platform or ship
