Аннотация:An oscillating shear flow of suspensions is considered as a case of a periodically varying shear flow similar to a stationary shear flow. In the structural rheological model, the dependence of the dynamic moduli on the cyclic frequency is explained as a result of changes in the structure of the dispersed system. The use of the equations of the structural rheological model makes it possible to describe the dependences of the loss modulus and the accumulation modulus on the shear vibration frequency without using mechanical models of the damper and the spring. The possibility of applying the structural model to suspensions of particles of various origins and the method of stabilizing the suspension is shown. The presence of different modes of the oscillating flow in individual frequency intervals is xplained by the nature of the change in the structure ofdisperse systems under the action of shear.
