An orthogonal experiment study on dynamic characteristics of a swing polishing grinding head

设计并搭建了摆动式抛光磨头动力学特性实验平台。通过加速度传感器测量磨头工作时的振动信号,基于磨头工作时的振动影响因素,开展了以磨头主轴转速、磨头压力和磨块粒度号三个参数为因素的正交试验,通过分析对比试验数据及信号瀑布图,得到以抑制振动为目的的最佳匹配抛光参数。试验研究结果为摆动式抛光磨头在抛光机上的应用提供参考。

An experimental platform of dynamic characteristics of a swinging polishing grinding head was designed and built.The vibration signals of the grinding head were measured by an acceleration sensor.Based on the factors affecting the vibration of the grinding head,orthogonal experiments were carried out based on three parameters of grinding spindle speed,grinding head pressure,and grinding block size.By analyzing and comparing the experimental data and the waterfall chart,optimum matching polishing parameters were obtained for suppressing the vibration.The experimental results provide a useful reference for the application of the swing polishing grinding head on polishing machines.
