电磁滑环式在线动平衡系统特性分析与实验
Performance Analysis and Experiment of Electromagnetic Ring Balancer During Operation

为了测试一种电磁滑环式在线动平衡装置的平衡特性，搭建了实验平台，采用影响系数法进行在线动平衡实验研究。主要从实验平台本身的振动特性、主轴转速对平衡效果的影响以及试加配重的角度对平衡效果的影响3个方面进行了分析研究，得到了实验平台和主轴转速对在线动平衡系统的影响，以及试加配重位置的选择方式，为高速主轴双面动平衡和模态分析的研究打下基础。
High-speed CNC machine is a kind of important scientific and industrial equipment. The spindle is a key component of the machine and the automatic balancing is important. An experiment platform has been built to test the properties of an electromagnetic ring balancer. Balancing test which uses influence coefficient method, mainly analyses from the following three aspects: Vibration test on platform itself; effects of rotating speed; effects of the angle of test weight. The experiment used an advanced automatic balancer and classical influence coefficient method. The results show the effects of platform and spindle speed, also get a simple way to get a good influence coefficient. A foundation has been built for two-plane balancing and modal analysis.
