Dynamic Analysis of Standing Wave Type Linear Ultrasonic Motor Based on Finite Element Method
摘要
Abstract
The dynamics of a standing wave type linear ultrasonic motor was studied based on finite element method.The three-dimensional finite element model of the motor was established,based on which the modal analysis was conducted.The resonance frequency of the first order transverse bending vibration was obtained,and the impact of the driving feet position on the resonance frequency was analyzed.On the basis of modal analysis,high frequency alternative current was then applied to the motor,and harmonic analysis was conducted.The amplitudes of transverse bending vibration stimulated by the applied source as well as the trajectories of the driving tips were investigated.A prototype of the standing wave type linear ultrasonic motor was fabricated and its impedance-frequency characteristic was measured.The measurement results verified the analytical results.关键词
