Online Performance Measurement Arithmetic Research and Application on Novel Swing Movable Teeth Transmission System

Principle and arithmetic of rotary machine torque measurement using virtual instrument technology are researched in this paper. A new method about torque measure with frequency tracing based on phase difference is presented. Part noise component are separated effectively from useful signal using self characteristic of correlation and sine function. Random disturbance immunity and measurement accuracy are enhanced. Applying generalized forecast method, make sampling frequency tracing frequency variety of measured signal, complete alternation sampling is completed and measurement precision can be guaranteed. A new torque revolution measuring instrument with VI technology is designed which has the advantage of self defining, powerful data processing ability and easily embedded digital compensation to realize automation measurement of torque and power of swing movable teeth transmission.
