| Abstract: | In this paper , the constitutive equations of SMA material proposed by Brision is adopted to investigate the dynamic response of shape memory alloy actuator under three types of heat transferring models: resistive heating with free convection cooling , resistive heating with forced convection cooling and the semiconductor “heat pump” modules. Meanwhile, the loading influences on the period of completing transformation are analyzed. The results indicate that heat transferring types will yield larger influen... |
