A STUDY OF ROAD ROUGHNESS EVALUATION FROM VIEWPOINT OF WHEELCHAIR USERS AND AGED PERSONS

本研究提出了一种从轮椅使用者和老年人的角度来评估道路不平整度的方法。1997年，该研究提出了一种从轮椅使用者的角度评估道路不平度的方法。讨论了两种类型的轮椅使用者的抱怨，一种可能是由内脏共振引起的，另一种是由刺激损伤的脊柱引起的。本研究通过实地测试量化了两者的感知功能。提出了人-轮椅系统模型，计算了轮椅在不同粗糙度路面上运动引起的振动。1996年的实验结果表明，人与老年人在步行量和从路面到脚趾的最小距离上差异不大。

This study proposes a method to evaluate road roughness from the viewpoint of wheelchair users and aged persons.In 1997, the study proposed a method to evaluate road roughness from the viewpoint of wheelchair users. Two types of wheelchair users' complaints were discussed, one may have been derived from viscere resonance and the other is derived from stimuli to damaged spinal colum. The study quantified perceptive functions of the two through field tests. The study also proposed a model of man-wheelchair system to calculate the vibration of wheelcair caused by motion on road with various roughness.It was revealed that there was not much difference of both footstep and minimum distance from road roughness to toes between man and old persons age by experiment in 1996.
