针对轮毂跳动量检测系统结构,分析了影响系统检测精度的误差来源,通过对引起误差结构的建模与分析,根据结构原理,得到回转主轴倾角与轮毂径向、轴向跳动量之间函数关系以及由于轮毂安装偏心引起的径向跳动随旋转角度周期性变化的函数.通过Matlab仿真和控制变量分析,验证理论,为检测系统的精密装配和调试提供了理论依据,对减小系统误差具有实际意义.%According wheel runout detection system,this paper analyzes the error sources affecting the system measure-ment accuracy. Through modeling and analyzing the errors caused by the structure,according to the structural principle, we get the rotation angle of the spindle hub radial, axial runout between function, and because wheel mounting radial eccentricity caused by the beating with the rotation angle of periodically varying functions. We verified the theory through the Matlab simulation and control variables. It provides a theoretical basis for assembling and installing the de-tection system,and it has practical significance in reducing systematic errors.
