Method of Vibration-proof Speed Measurement Based on Optical Encoder

The influence of vibration of transmission shaft on output signals of encoder was introduced and provided a way to distinguish the output interference impulses of optical encoder.Integrated with M/T speed testing method,a new method of vibration-proof speed and direction testing was formed.In the meantime the result of the experiment indicate that compared with traditional speed testing,this method of vibration-proof speed testing is effective in that it can enlarge the area of speed testing and is more accurate,thus being practically valuable.
