000015318 520__ $$2eng$$aJump phenomena of rotational angle and temperature for a nonlinear torsional vibration system with phase transformable NiTi wire are investigated in the frequency, amplitude and time domains. At fixed excitation amplitude, jump phenomena of thermomechanical responses are identified on the FRC by monotonically changing the excitation frequency. Similarly, by sweeping the excitation amplitude with small intervals, jump phenomena are captured in the amplitude domain. Under critical external excitations, spontaneous jumping process from the lower branch to the alternative upper branch is identified by experiments in the time domain.  ...  jump phenomena are directly affected by the external excitation and disturbance. External excitation changes the magnitude of thermomechanical responses and further determines the nonlinearity and damping capacity of the dynamic system. Accumulation of internal and external disturbance triggers the jump phenomena in the time domain, revealing the nonlinear dynamic instabilities of the system with NiTi SMA.
