The first part of this paper deals with the finite element simulation of a slant cantilever beam, and the second part contains an approximate equation formula of its resonance frequency. We investigated such vibrational behaviors of a slant cantilever beam because we had to design a large-diameter torsional vibrator with many slant slits cut into its end-face for a rod-type ultrasonic motor. Also, we thought that the simulated and investigated results on the slant cantilever beam might be very useful in other applications, for example, vibrational sensors. In this paper, therefore, we present some finite element simulations of a slant cantilever beam and we investigate the results of its approximate equation formula, as academic research material.
