| 摘 要： | 管道内检测机器人的结构形状是影响其运动学、动力学特性的关键因素,在机器人设计中占有重要地位。在合理提出一些基本假设后,用二阶迎风差分格式离散管道内检测机器人附近流场的控制方程,并用SIMPLE算法求解,得到了7种不同形状的管道内检测机器人所受的差压驱动力及其周围的流场信息,并对这几种结构的CFD特性作了比较。最后综合空化条件、驱动力、腔内有效体积和加工难度等因素,确定了上游半球形结构为设计形状。

| Abstract: | The shape of in-pipe robot is the key factor influencing its kinematic and dynamic behaviors and plays an important role in robot design. On the basis of some reasonable assumptions, the governing equations of in - pipe flow field around robot of seven different shapes are discretized with second order upwind scheme and solved by SIMPLE algorithm, and then their CFD features are compared. After taking into full consideration the factors such as condition of cavitation, drive force, available volume, and the difficulty of manufacturing, the shape of semi-ball at upstream is selected. |
