Abstract

Underwater launchers are typically employed for the deployment of pigging robots in subsea pipelines for the purposes of cleaning and inspection. Throughout the launching process, challenges related to vibration, damage, and other issues must be addressed and resolved. In this study, the launching process of the pigging robot is numerically simulated using Abaqus 2020. Utilising the Coupled Eulerian-Lagrangian (CEL) method, the Fluid-Structure-Interaction (FSI) model of the launching process was constructed. And the variation of parameters such as velocity, friction force and tilt angle at different inlet flow rates were analysed. The findings indicate a positive correlation between the average velocity of the pigging robot and the inlet flow rate. The factors such as friction, tilt angle, and offset distance are related to the motion process of the pigging robot. Furthermore, during the pigging robot’s traversal through narrow pipe sections, the sealing discs undergo irregular deformation, generating a reaction force on the robot and inducing vibration. In conclusion, the analysis of the impact of inlet flow velocity on the motion behaviour of the pigging robot offers a theoretical foundation and reference for the successful launch of the robot.

使用欧拉-拉格朗日耦合方法研究海底输油管道中双向注油机器人水下发射过程的力学行为

水下发射器通常用于在海底管道中部署管道清洗和检查机器人。在整个发射过程中，必须应对和解决与振动、损坏和其他问题相关的挑战。在本研究中，使用 Abaqus 2020 对装载机器人的发射过程进行了数值模拟。利用欧拉-拉格朗日耦合（CEL）方法，构建了发射过程的流体-结构-相互作用（FSI）模型。分析了不同入口流速下速度、摩擦力和倾斜角等参数的变化。研究结果表明，喷涂机器人的平均速度与入口流速呈正相关。摩擦力、倾斜角和偏移距离等因素与挖泥机器人的运动过程有关。此外，在穿管机器人穿越狭窄管段的过程中，密封盘会发生不规则变形，对机器人产生反作用力并引起振动。总之，分析入口流速对注塑机器人运动行为的影响，为成功推出注塑机器人提供了理论基础和参考。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
