| This work is concerned with the problem of nonlinear dynamical motion of a non-ideal autoparametric system with two active elements – shape memory alloys (SMA) spring and the magnetorheological (MR) pin joint dampers in the neighbourhood internal and external resonance. A polynomial constitutive model was assumed to describe the behaviour of SMA’s spring and there was observed the pseudoelastic eflfects associated with martensitic phase transformations. The simplified resistance moment generated by the MR pin joint can be approximated using the hyperbolic tangent flinction. The influence of damping forces in MR dampers on the phenomenon of energy transfer and pseudoelastic effects associated with the martens might excite or damp another mode, and that except different kinds of periodic vibrations there may also appear chaotic vibrations. For the identification of the responses of the system various techniques, including chaos techniques such as bifurcation diagrams and time histories, power spectra densities (FFT), Poincarè maps and exponents of Lyapunov may be used. The SMA spring and MR damper can be used to change the dynamie behaviour of the autoparametric system giving reliable semiactive control possibilities |
