摘要/Abstract

摘要： 大多数水平井爬行器采用双电机控制方式。针对该方式存在能耗较高、发热量大和控制复杂等问题，设计了一款电永磁吸盘以保证滚轮与油管壁之间产生足够的正压力，从而仅由单电机便可驱动爬行器。利用有限元方法对该电永磁吸盘进行了电磁学仿真计算，分析讨论了多个尺寸参数对充退磁性能的影响，最终选取了一组较为合理的尺寸参数。试验表明,实测值与仿真值之间的误差小于15%，爬行器能够产生3000N以上的牵引力。

Abstract: Most tractors used two motors to control, and led to high energy consumption, large heat release and complex control. Due to these problems, an electropermanent magnet sucker was designed to provide enough normal forces between wheels and the pipe walls. So, the tractor might be drived by only one motor. The finite element method was used to simulate the electropermanent magnet suckers, which analyzed the impacts of various size parameters on the magnetization and demagnetization performances. Based on the simulation results, a group of reasonable size parameters was selected. The errors between the actual values and the simulated values are less than 15% by the experiments of the electropermanent magnet sucker, and the well tractor with electropermanent magnet sucker may drag over 3 000N.

Key words: horizontal well, well tractor, electropermanent magnet, normal force
