Analysis of the Electromagnetic Force Generating a Cricular Movement and Vibration Characteristic for an Orbital Friction Vibration Actuator
Orbital Friction Vibration Actuator (OFVA) is a core component of Orbital Friction Welding (OFW),which is a novel apertureless welding technology utilizing friction heat to implement solid-state.By taking advantage of the special electromagnetic structure,OFVA can produce a contactless,radial,synchronous and rotating force with adjustable amplitude and phase upon the still mover which then vibrate according to the predetermined orbital.This paper analyzes the operational principle and structure of OFVA and conducts a mathematical analysis for a core issue about how to make the motion component of the OFVA generate circular moving trajectories.Vibration characteristic are analyzed and the expressions of amplitude amplification factors as the moving component is moving in a circle are derived.
