EFFECT OF JOINT OF TILE PAVEMENT ON VIBRATION OF WHEEL CHAIR AND COMFORT OF SEATED PERSON

Abstract

Basic characteristics of the vibration of a running wheel chair on tile pavement and effects of width of joint and joint spacing of tile pavement were revealed by using of the vibration acceleration of seat of the wheel chair. Vibration level of the wheel chair was calculated by considering the frequency-weighted acceleration values, and the wheel chair vibration and the comfort of a seated person were evaluated according to ISO2631(1978). Furthermore, an estimate method of vibration level of the running wheel chair on arbitrary tile pavement was suggested, and the relation between the comfort of a seated person on the wheel chair and the dimension of tile pavement were figured out.
