摘要

利用基于关联维数的相位随机化的替代数据算法,对不同键合压力下超声换能系统中换能杆末端轴向振动的实测数据进行正确替代,并用非线性动力学的理论来检验其是否具有非线性。通过实验对所测振动时间序列的关联维数进行计算,结果表明在实际键合过程中,不同键合压力下变幅杆末端轴向振动都具有非线性成分。这有利于更好地认识超声引线键合换能系统,并为进一步利用非线性时间序列分析方法研究引线键合过程中的复杂振动提供了深入分析的科学手段。

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.
