Abstract
The purpose of this paper is to investigate the effect of the hand coupling actions (grip-only action and combined grip and push action) on the temporary threshold shift (TTS) of vibrotactile perception on a fingertip. Twelve subjects participated in the experiment. Six exposure treatments were used in the experiment, which are composed of two sinusoidal vibration exposure frequencies (16, 125 Hz), one control exposure condition (0 Hz), and two hand coupling actions (20 N grip-only and combined 20 N grip and 40 N push). The subjects were exposed to constant ISO weighted acceleration of 8 m/s2 rms of 5 minutes duration for each vibration condition. The TTS was measured before and after each subject was exposed to vibration. This study found that the TTS is affected by the coupling action at the exposure frequency of 125 Hz.
