Abstract

A simulation method is presented for the estimation of the parameters which characterize the forcedbending vibration of a strip of textile fabric, such as the constants related to the hysteresis and damping; a nolinear least-squares-method is adopted to consider the nonlinearity inherent to the phenomena, and the stability of estimation as well as the influence of experimental error on the estimation are examined. The amplitude-fre-quency dependency obtained by experiment could be sufficiently reproduced from the parameters estimated by this method. In the estimation of the whole curve of hysteresis, the accuracy was not so good but could be fairly improved if the rigidity data at higher curvatures were incorporated as auxiliary information.
