진동대 실험을 통한 수평진동 체감도 평가

In this paper, threshold of motion perception for horizontal vibration was estimated by one-dimensional shaking table. After investigating preceding studies in foreign countries, a suitable course of experiments was organized. We used one-dimensional shaking table for horizontal vibration tests, and a vibration house made similar to a living space was made. Experimental results were recorded by increasing acceleration in the range of 0.2㎐ through 1.2㎐ of frequency after organized into five experimental groups, each of which was composed of eight persons. We obtained performance curves by dividing the distribution of perception from horizontal vibration tests into the range of 0~20%, 21~40%, 41~60%, 61~80%, 81~100% and then fitting curves. Also we made questionnaire based on human comfort criteria of foreign countries, and examined the feeling of subjects. From the results of horizontal vibration tests, it was found that acceleration of perception was low when frequency was high, and that visual and auditory senses affects the human perception for horizontal vibration.
