摘要
本文用频谱分析和自回归谱分析的方法对形状误差、波度和表面粗糙度的划分进行了探讨,并根据实验和谱分析的结果,初步确定了划分的截止频率和过渡范围,与有关的结论进行了比较。在比基础上计算了低通、高通和带通滤波器的传递函数。
In this paper, the frequency spectrum and the autoregressive spectrum analyses are applied to distinguish the different frequency hands for form error, waviness and surface roughness. In the light of the results of the experiment and the spectrum analyses, the limiting frequencies and the ranges of transition are determined approximately, which are compared with the corresponding standards. On these hases, the transfer function of the low-, high- and band-pass filter is computed respectively.
