The Study of Magnetic Circuit Control Technology for Permanent Magnet Hump Rail Brake

摘要

This paper introduced a hump rail brake equipment which used the Nd-Fe-B permanent magnet as the energy source of brake force and the control theory of the magnetic circuit. The paper focused on bringing forward a design theory and methods of the key permanent magnetic parts, calculated the magnetic circuit and simulated the magnetic system with the ANSYS software. Through analyzing the results of the machined model parts, this equipment reached the actual application level and provided a new economic energy solving scheme for hump velocity control.
