How to detect and remove unwanted asperities is a critical problem in the dynamic measurement Measurement of discontinuous curves is the dynamic measurement of discrete points, and results frequently in unwanted asperities. Meanwhile, the measurement sample is not big. Based on the features of the grey theory, a modified Grey Model is introduced to approach the measurement data. Combined with the robust minimum deviation principle, a method using grey theory to detect unwanted asperities in the dynamic measurement is studied. All the equations and the distinguishing criterion are given.

针对非连续曲面测量中易产生异常数据,数据样本不大等特点,引入一种改良型灰色模型,结合鲁棒性较好的最小一乘法,提出了非连续曲面动态测量中异常数据的灰色理论判别法;给出了全部算式及判别准则,并根据滚刀啮合误差的实测数据进行了验证计算。

The analysis methods of data validity in simulation model validation are presented. The statistical analysis, such as the Grubbs criterion and the t test criterion, can be used for validation of measured data, while the nonstatistical analysis, such as the entropy discrimination method and the gray theory discrimination method,should be adopted under the condition that the number of samples is small and the distribution is unknown. Finally, examples are given to illustrate the use of these methods.

给出在仿真模型确认中的数据有效性分析方法.对于测量数据可采用统计的方法,如Grubbs准则和t检验准则;在小样本未知分布的情况下,可采用非统计方法,如信息熵判别法和灰色理论判别法.通过实例说明这些方法的应用.这些方法的使用有助于仿真模型确认的研究.
