摘要
差压式管道内检测机器人是利用管道中流动介质压力差驱动的检测装置，机器人受力情况及周围流场分布对其运动状态有着重要的影响。通过对检测机器人受力分析和数值模拟，讨论了影响给定机器人驱动力的主要因素，得到了以水为流动介质在水平管道情况下，水流速度与机器人稳态速度的近似关系式，为以后进一步研究机器人定位提供帮助。
Differential-pressure-driven in-pipe inspection robot is a detection device driven by pressure-difference of fluid medium itself in the pipeline. Robot force situation and the distribution of the flow field around it have an important impact on its motion state. In this paper, the authors discuss the main impact factors of driving force of a given robot by force analysis and numerical simulation with Fluent, and obtain the approximate relationship between the flow speed and the steady-state speed of robot making the water as the mobile medium in the horizontal pipe, and provide the help with the further study of robot positioning.
