The Research on the Computational Method of Cam Lift in Auto Measuring Instrument for the Cam Shaft

论述了凸轮轴自动检测仪计算机软件系统中的凸轮对称中心线寻优法,各采样点绝对升程值获取法以及利用N次谐波曲线拟合法求取凸轮节点升程误差及误差曲线。

In this paper,the seeking optimum method for determining symmetrical axis of cam, the method for acquiring the obsolute lift value of every sampling-point on cam, and the method for obtaining the lift error of node on cam as well as curve of lift error by fitting with N order harmonic components are described. These methods, mentioned above consist of the computational methods for cam lift error by the computer controlling multi-measuring probes instrument for auto-measuring cam shaft.
