Research on the Principle of Suspension-Type Needle Selection and Its Modeling

This paper has proposed a kind of suspension-type needle selecting device,designed its 3D model method and the needle alignment on the circular knitting machine. By making finite element analysis on suspension-type needles based on the driving principles, we can get the needles’ force situation and available thickness under conditions of different permanent-magnet thickness and air gaps. The dynamic response experiment model of the suspension-type needle is also given.
