Overview

Finite element analysis quantifies vibration responses of head positions under fore-aft vibration, indicating comfort differences.

Key Points

  • The aim is to examine how different positions of the human head respond to fore-aft whole-body vibration.
  • Conducted modal and random response analysis on a finite element model
  • Analyzed vibration behavior in the frequency range of 0-20 Hz
  • Evaluated transmissibility from seat to different head positions
  • Identified two main peaks in transmissibility at 0.76 Hz and 2.74 Hz on the direct axis
  • Noted substantial decreases in peak values from the top of the head to the sides
  • Cross-axis maxima and minima observed at the forehead and crown, respectively
