Resonance Frequency of Vibrating Resonator Deformed by Axial Force

In this paper, the resonance frequency of a vibrating resonator used as a force sensor has been considered. The value of resonance frequency change of the resonator deformed by the axial force is calculated using the finite element method. Then, the resonance frequency change considering the stress distribution of the resonator by the axial force is also calculated. The difference between the two kinds of resonance frequency changes is quantitatively clarified.
