doi:10.3901/JME.2021.19.014

Abstract

Abstract: A proportional electromagnetic dynamic vibration absorber (EDVA) consisting of a actuator and an elastic element is proposed. The dynamic characteristics of the EDVA show asymmetric variations in driving force, which is due to effect of the changing air gap on magnetic force. The design of the proportional electromagnetic actuator is realized considering the geometric parameters of the core to achieve nearly constant magnetic force over a broad range of its dynamic displacement but proportional to square of the current. The effects of various geometric parameters of the core such as width and slope of the iron core, and the air gaps on the resulting magnetic force characteristics are evaluated using a finite element model, and verified experimentally. The static equilibrium position of moving core is analyzed considering the dynamic displacement characteristics of absorber mass, and the results are obtained considering the demand driving force, operating frequency range and the desired relative displacement range(2～7 mm). The absorber stiffness is discussed rely on the ratio of the magnetic force to the driving force magnitudes. Finally, a prototype proportional EDVA was subsequently designed, and the driving force are calculated and verified experimentally. The results show that the proposed proportional EDVA yields nearly symmetric driving force response.
