Abstract:

: A two-layer compliant structure is considered. One of its layers consists of a magnetosensitive elastomer, while the other layer is made of a pure elastomer. Young and shear modulus in the magneto-sensitive layer depend on the magnitude of the applied magnetic field which change periodically in time. The theoretical investigations are dedicated to modeling the problem as a two-layer Timoshenko beam. By the method of averaging the expressions for the amplitude and phase of the steady-state vibrations of the beam are obtained. The results of the analytical investigations are confirmed by numerical calculations. The mechanical system under consideration can be regarded as a model of a tactile sensor or a gripping element in soft robotics.

Keywords: multi-layer cantilever beam; sandwich structures; soft robotics; tactile sensors; method of averaging.
