Vibration Performance Analysis of Electromagnetic Resonance Fatigue Testing System

Abstract:

Vibration property studies are fundamental works for dynamic force calibration of fatigue testing machines. Taking the electromagnetic resonance fatigue testing machine as an example, we performed modal analysis based on finite element method and the vibration modes were fully understood. Furthermore, we analyzed the influence of vibration mass variations, i.e. mass loaded and geometrical error of specimen, on the natural frequency and force coaxiality of the system. Increasing the weights loaded results in the decrease of natural frequency of the system, while increasing the cross-sectional dimension of specimen gauge leads to the increase of natural frequency and the force coaxiality.
