Characteristics of Perception on Random Horizontal Vibration Containing Predominant Frequency Waves to the Same Degree

Abstract

In this study, we performed an experiment for random vibration containing predominant frequency waves to the same degree. The objective was to investigate the influence of the characteristics of perceptual frequency of the random vibration based on the component of a complex vibration. Results show that the effects due to the difference of the waveform pattern on random vibration in the range of 30 % to 50 % of the subjects probability of perception have less impact but it's more than that at a 10 % and 90 % rate of probability of perception.
