조향 휠의 회전진동이 인체에 미치는 영향

In order to find human responses to rotational vibration of a steering wheel, a steering wheel system was excited by sinusoidal signals in the frequency range from 8 to 100Hz. Two accelerometers were mounted on the steering wheel to measure the acceleration signals experienced by the subject who provided an assessment of subjective discomfort. Equal sensation contours were determined between the measured accelerations and the median values of the subjective assessments of 12 subjects using psychophysical power law.
