Fluid-solid-soil multi-phase coupled six-freedom degree unidirectional/bidirectional static/dynamic loading instrument

Abstract

The invention relates to a fluid-solid-soil multi-phase coupled six-freedom degree unidirectional / bidirectional static / dynamic loading instrument. The loading instrument comprises a support rack. The support rack is provided with a first servo motor, a second servo motor, a third servo motor and a linear module. The first servo motor and the second servo motor are arranged along a vertical direction of the support rack and the third servo motor is arranged along a horizontal direction of the support rack. A signal connection wire is connected to the linear module. The other end of the signal connection wire is connected to a PLC control system. The loading instrument is a soil test device, realizes six-freedom degree coupled loading in a space, realizes a soil model test in a marine engineering field, utilizes double closed-loop auto-control, has a self-developed six-freedom degree loading program, improves the existing one or two freedom degree soil loading instrument used in the current self-elevating platform pile insertion and pulling, is convenient for use and has good effects.

Description

technical field [0001] The invention relates to a fluid-solid-soil multi-coupled six-degree-of-freedom single- and two-way static and dynamic loading instrument, which belongs to the technical field of hydraulic engineering experiments. Background technique [0002] At present, in the process of researching jack-up platform plugging piles at home and abroad, the vertical loading mode with a single degree of freedom is adopted, and multi-degree-of-freedom loading in the horizontal direction and rotational direction is not realized. In order to simulate ocean hydrodynamics more accurately load, it is necessary to embed a multi-degree-of-freedom coupling loading control system in the test equipment, and reasonably design the ideal mechanical loading equipment. The present invention proposes and develops based on the above-mentioned key technologies. Contents of the invention [0003] The purpose of the present invention is to provide a fluid-solid-soil multi-coupled six-degr...
