Abstract

Surrogate-data method of phase-randomized based on correlation dimension was proposed to surrogate the data of the amplitude transformer terminal in the axial direction, which were tested in different pressures, and then the nonlinear dynamic theory was checked whether the data contained the nonlinear factor. The result indicate there are nonlinear factors in the axial direction of the amplitude transformer terminal, after calculating the correlation dimension of the tested data, when ultrasonic bonding system is loaded different pressures. It is helpful for understanding of transducer and provides analytic science instrument for further study of the vibration in ultrasonic wire bonding with the nonlinear time series method.
