A Study on Characteristics Evaluation of Fiber Material Using High Sensitivity Force Plate

Abstract

This paper proposes the estimation method of friction coefficients using the high sensitivity force plate. This force plate can measure 3-axis force, 3-axis moment and COP (center of pressure). The proposed method estimates coulomb and viscous friction coefficients by using the shear force, the normal force and the velocity of force plate data. The velocity is calculated by differentiating the COP information. The friction coefficients are modeled as the values proportioning to the normal force. The estimation method conducted by the Kalman filter. We conducted the measurement experiment using the force plate and the 5 type clothes, and we estimated the coulomb and viscous friction coefficients between the finger and clothes. The analytical results showed the difference by clothes, the change of friction coefficients was indicated.
