Foot-Transmitted Vibration: Automotive Accelerator Pedal-Pad Vibration on Tarmac and Paved Road

Vibration at the pedal-pad may contribute to the discomfort of the foot plantar fascia during driving. In this study, the experiment is conducted using a “five-time repeatability” test of the same procedure and shall determine root-mean-square vibration magnitude and vibration transmissibility on Z-...
