ABSTRACT:
Device for measuring the rheological properties of a viscoelastic material, formed of an upper rotating plate (10) and of a lower rotating plate (20) which are able to press against the opposite faces of a sample S of the material to be measured. The axes of rotation (a1a1′ and a2a2′) of said plates are arranged parallel to one another in a direction perpendicular to the plane formed by the plates, and offset from one another by a distance d. Two independent motors (12, 22) drive respectively the upper plate (10) and the lower plate (20) at the same speed of rotation ω, without giving rise to any angular displacement between the two plates.
