Nonlinear dynamic characteristics of SMA gripper under bounded noise

Nonlinear dynamic characteristics of SMA gripper under bounded noise

A kind of constitutive model of SMA is proposed in this paper, and the nonlinear dynamic response of a SMA gripper under bounded noise is studied. The harmonic driving signals and the random disturbance made up of bounded noise. The dynamic model of the system is established by Hamilton principle. T...
