A mathematical model for the strain–temperature hysteresis of shape memory alloy actuators
AbstractIn this paper, a new hysteresis model based on the limiting loop proximity (L2P) approach is proposed to describe this phenomenon in the strain (&z.epsiv;)–temperature (T) characteristics of shape memory alloy (SMA) actuators including major and minor loops. In order to validate the proposed model, an experimental set-up was especially designed and implemented aim at to determine the &z.epsiv;–T behavior of Ni-Ti SMA wire actuators under constant loads. The obtained results for &z.epsiv;–T loops are presented together with the data calculated with the proposed model. Model simulations have shown good agreement with the experimental data.
