Study on the smoothness of coupled mechanism along the track relative motion

Abstract

In this paper, two different coupling structures, including the plane winding of the transmitting coil and the vertical winding of the transmitting coil, are designed. A magnetic coupling mechanism with large transmission power is selected and the smoothness of the contactless power transmission(CPT) is also studied when the deviation occurs between the transmitting coil and the receiving coil. By means of ANSYS finite element simulation tool, the self-inductance and mutual inductance of the two kinds of coupled coupling coils are obtained, and the change of transmission power of the coupling mechanism along the relative motion of the track is also simulated. The two coupling mechanisms were made in the experiment. Finally, a magnetic coupling mechanism with strong transmission capability was selected, and the results show that the system can be able to maintain good smoothness.
