摘要
为提高检测机器人的吸附性能并降低机器人的重量,本研究采用有限元仿真、数值拟合和人工蜂群算法对永磁吸附单元进行了设计与优化.设计了 3 种不同的磁路,利用Ansoft Maxwell仿真软件分析了不同磁路的吸附性能,结果表明,与传统H形磁路相比Halbach磁路具有更优异的性能,对于Halbach阵列,当永磁体宽度、厚度一定时,随着垂直磁化永磁体长度的增大,磁吸附力先增大后减小.利用人工蜂群算法对磁路进行了参数优化,参数优化后的磁吸附单元体积减小,单位质量磁吸附力增大.基于机器人本体开展功能验证实验,实验结果证明爬壁机器人能在任意工作位置下稳定运行.
Abstract
In order to improve the adsorption performance of the detection robot and reduce the weight of the robot,the permanent magnet adsorption unit is designed and optimized through finite element simulation,numerical fitting and artificial bee colony algorithm in this study.Three different magnetic circuits are designed,and the Ansoft Maxwell simulation software is used to analyze the adsorption properties of different magnetic circuits,which demonstrates that the Halbach magnetic circuit has better performance than traditional H-shaped magnetic circuit.For the Halbach array,when the width and thickness of the permanent magnet are unchanged,the magnetic adsorption force first increases and then decreases with the increase of the length of the vertically magnetized permanent magnet.After the parameter optimization of the magnetic circuit through the artificial bee colony algorithm,the magnetic adsorption unit volume decreases while the magnetic adsorption force per unit mass increases.The functional verification experiments based on the robot body show that the wall-climbing robot can run stably in any working position.
