【Abstract】 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.更多还原
