Study and simulation of the model about high-speed maglev Drive needles

摘要

Based on the magnetic suspension theory,this paper has proposed a kind of suspension-type jacquard needle driving principle,and designed its 3-dimension model method.By making finite element analysis on suspension-type needles,analyzing the experimental data and designing the structure,we can get the relationship among related parameters under conditions of different permanent-magnet thickness and air gaps,which can provide criteria in theory and application for designing on new needle driving principle,control system and needle.
