209 Identification Method of Propagation Characteristics of Pulse Wave in Viscoelastic duct

Abstract

This paper shows two identification methods of propagation characteristics of pulse wave in viscoelastic duct. One method identifies material parameters of viscoelastic duct by measuring pressures at three points and flow volume at one point. The other method identifies them by measuring pressures at four points. Material parameters of the same silicon tube were calculated by two methods. And reasonability of two proposed method was confirmed by comparison of two calculated material parameters.
