Apparatus used for simulating ocean environment load

Abstract

An apparatus used for simulating an ocean environment load comprises reaction frames and loading units of a length and width directions, an ocean conduit frame platform model, a computer system and a servo driver. The loading unit of the length direction applies a horizontal load along a model length direction, and the loading unit of the width direction applies a horizontal load along a model width direction. The loading units of the two directions comprise servo electric cylinders formed by servo motors and actuators, front end and rear end connection boards, front end and rear end spherical hinge assemblies and displacement and pressure sensors. The reaction frames are connected to a ground concrete foundation. An upper end is connected to a rear end connection plate of a loading device through welding so that a support effect is achieved. The computer system sets a load parameter and a PID adjusting parameter according to a requirement, emits an instruction to the servo driver and receives collected data. The apparatus can apply rule wave or random wave loads with different parameters on a model and possesses characteristics of shock resistance performance, a long service life and simple operation and maintenance.

Description

technical field [0001] The invention relates to a marine environment load simulation device for a jacket ocean platform model. Background technique [0002] Model experiment is an important means of ocean engineering hydrodynamics research. Currently implemented offshore platforms must be modeled experimentally before and after design, simulating real wind, waves and other marine environmental conditions in marine engineering pools to predict their dynamic characteristics in real marine environments. With the development of ocean engineering technology, engineers and technicians put forward higher requirements for model experiments on ocean platforms. In some marine working conditions with relatively high wind speed, wind load and wave load have a significant impact on platform performance, so the wind load and wave load on the platform need to be accurately simulated. These loads are often changing, and the response of the platform model is also constantly changing. How t...

AI Technical Summary

Problems solved by technology

This device uses an electric winch to apply tension to the model to simulate the wind, wave, and current environmental loads on the model. Although the simulation of unsteady loads can be realized, the point of action of the actual environmental load is different. Due to the gravity and characteristics of the cable itself The effect of the pull force is not equal to the load applied to the model, so precise control cannot be achieved
