摘要

在粘弹性介质近似流变模型中，研究了摩擦过程中冰软化的自仿射模式。研究了由表面液体层形成决定的冰摩擦的不同模式。对摩擦力的时间序列进行分析，即傅里叶分析、构建自相关函数和差分自相关函数。对结晶冰的模式以及稳定冰和亚稳软化冰的混合模式进行了光谱幂律检测。证明了相应摩擦力时间序列的自相似性和非周期性。

Time series analysis of friction force at self-affine mode of ice surface softening

The self-affine mode of ice softening during friction is investigated within the rheological model for viscoelastic medium approximation. The different modes of ice rubbing, determined by formation of surface liquid-like layer, are studied. The analysis of time series of friction force is carried out, namely Fourier analysis, construction of autocorrelation and difference autocorrelation functions. The spectral power law is detected for modes of crystalline ice as well as of a mixture of stable ice and metastable softening. The self-similarity and aperiodic character of corresponding time series of friction force are proved.
