In this paper, a kind of shape memory alloy (SMA) model based on multivariate statistical analysis was developed and applied in studying the vibration characteristic of SMA intravascular stent in blood stream field. Hysteretic nonlinear theory was introduced to interpret the difference between loading and unloading curve of SMA. Multivariate statistical analysis method was applied in finding the relationship...
In this paper, a kind of shape memory alloy (SMA) model based on hysteretic nonlinear theory and data mining was developed and applied in vibration control on rotor system with SMA bearing. Nonlinear difference item was introduced to interpret the hysteretic phenomenon of SMA. Arctangent function was introduced to describe the variation of SMA stiffness with temperature. Based on above, all of possible...
In this paper, the nonlinear dynamic characteristics of vehicle semi-active suspension system with SMA spring was studied. SMA spring was applied in semi-active suspension system to substitute ER and MR fluid to provide controllable force. Hysteretic cycle and multinomial model were introduced to set up a new kind of continuous SMA strain-stress-temperature model, based on which the nonlinear dynamic...
