摘要
This contribution deals with the analysis of a rotordynamic nonsmooth shape memory alloy (SMA) system. The rotor-bearing system is modeled as a Jeffcott rotor with two-degrees of freedom and discontinuous supports. Two different situations are investigated: linear elastic support and shape memory alloy support. Numerical simulations are carried out establishing a comparison between elastic and SMA systems, showing situations where nonlinear effects of SMAs are interesting in dynamical responses avoiding undesirable behaviors. Temperature dependence of SMA response is investigated showing adaptive aspects of this kind of system.
