摘要：Detent force is an important factor affecting the running of permanent magnet suspension belt conveyor. Specific to detent force characteristics of the permanent magnet suspension belt conveyor, a finite element method was adopted to perform finite element analysis on a permanent magnet support system based on diverse air gaps, parameters of permanent magnets, and different kinds of clearances between permanent magnets. Not only was a method of defining the optimal buoyancy–resistance ratio for the permanent magnet suspension belt conveyor presented but also an optimized mathematical model for buoyancy–resistance ratio that takes velocity into account was established. Furthermore, a global optimal solution ( 1 . 6 m / s ) and a local optimal solution ( 11 . 83 m / s ) were both figured out for optimal speed of the magnetic belt. In this way, references could be provided for the permanent magnet suspension belt conveyor design.
