STUDY ON EXCITATION APPARATUS AND PERCEPTION APPARATUS FOR EVALUATING FLOOR VIBRATION CAUSED BY HUMAN WALKING : Development of "Impactive Excitation Apparatus" and verification of appropriateness of method to compute duration of vibration

Abstract

This paper presents the progress and the result of the development of "Impactive Excitaion Apparatus" based on vertical loads applied to floors while walking, to establish the appropriate measurement method of floor vibrations caused by walking. "Impactive Excitation Apparatus" is composed of a dropping weight and a rubber sheet, and it can reproduce floor vibrations caused by heel contact while walking. And we verify the appropriateness of a method to compute the duration of vibrations Th, which influences the human sense of vibrations, from the results measured by "Impactive Excitation Apparatus" and "Perception Apparatus" which was established in previous paper.
