摘要
利用Ｗ－Ｍ函数对二维表面粗糙度进行模拟，并利用其功率谱计算表面粗糙度的分形维数。最后分析了分形维数与表面的支承长度率曲线的关系。
In this paper, the 2 D surface roughness is simulated with W M function. Fractal dimension is calculated by the spectral density of W M function, and lastly the relationship between fractal dimension and the normalized bearing length ratio curve is analyzed.
