This paper considers the motion of a torsion viscosimeter that permits a conclusion about the rheological type of the liquid filling it. We have developed a theory of identification of nonlinear properties based on the use of the effective values of viscosity for each half-period and analytical solutions for linear liquids. The questions of the sensitivity that should be taken into account in planning an optimal experiment have been highlighted. © 2008 Springer Science+Business Media, Inc.
