Abstract

To analyze chatter vibration, dynamic stiffness of a rotating spindle in radial direction is important . In this paper, dynamic stiffness of a rotating spindle can be measured by using the magnet loader, which is a electromagnetic loading device.
 
Key words: dynamic characteristics, spindle stiffness, electromagnetic attractive force, magnet loader.
