Analysis on the Characteristics of Electromagnetic Force and Resonance Characteristic for an Orbital Friction Vibration Actuator Used in Orbital Vibration Welding

摘要

Orbital Friction Vibration Actuator (OFVA) is a core component of Orbital Friction Welding (OFW), which is a novel aperturclcss welding technology utilizing friction heat to implement solid-state joining. In this paper, topologies and operational principle of OFVA employ in OFW are introduced The characteristic of static and dynamic electromagnetic force is calculated by 3-dimensional finite element method. The dynamic simulation model is established. Simulation and experiment validate the accuracy of theoretical analysis and the feasibility of the fabricated prototype.
