凸轮轴在检测仪上的安装偏心,影响凸轮轴上凸轮廓形尺寸的测量精度。本文提出一种辨识被测凸轮轴安装偏心量的对径谐波法,证明了用对径谐波法所辨识的偏心量符合最小二乘准则。此法在实际测量中获得了满意的效果
Eccentric installation of the camshaft on the tester affects the measurement accuracy of the cam profile size on the camshaft. In this paper, a method of identifying the eccentricity of the measured camshaft is presented. It is proved that the eccentricity recognized by the diameter-harmonic method conforms to the least square criterion. This method in the actual measurement obtained satisfactory results
