A SIMPLIFIED METHOD TO IDENTIFY HUMAN WALKING FORCE BASED ON THE BODY RESPONSE SPECTRUM OBTAINED BY FFT ANALYSIS

Abstract

 The purpose of this study is to propose the simplified method to identify human walking force by using FFT power spectrum from the experimental acceleration data of the human body. An experiment on human walking is carried out on a stationary surface. Effectiveness of the proposed method is discussed for the measured acceleration data of the human body compared with the existing walking forces for both vertical and lateral component. It is pointed out that a little difference between men and women occur through the human walking on a stationary floor. These results also showed that the present method could identify the walking vertical and lateral forces with sufficient accuracy and less complexity.
