The paper deals with experimental analysis of hard rubber dynamic tests under finite torsion deformations. The experimental test rig based on controlled servo-motor was proposed and built for torsion straining of the rubbers under defined amplitudes and frequencies and temperature of angle vibration. The paper brings results of the tests for different excitation frequencies under different levels of torsion deformations. The mathematical rheological model of rubber is also presented for phenomenological description and parametric identification of hard rubbers.
