Effects of Drawing Speed on the Acoustic Emission Signals in Drawing

The speed of drawing has an important influence on drawing, so it can detect the process of drawing in different speeds by using acoustic emission testing technique. The purpose of this experiment is different amplitude of acoustic emission signals are studied in various velocities in the process of acoustic emission, through signals we can research that the relation of different kinds of friction-motion speed and amplitude of acoustic emission signal. The results showed that the speed of drawing has an important influence on amplitude of acoustic emission signal in the process of drawing. So it is concluded that with the aggrandizement of speed, amplitude of acoustic emission signals increases.
