Experimental Study of Angular Acceleration Sensor and Its Error Analysis
For shaft angular acceleration is the key to rotary system state inspection and fault analysis, two new angular acceleration sensors based on the principle of electromagnetic induction are presented. When the angular acceleration component exist in rotary system, this component is output in the form of induced potential through electromagnetic coupling. The output voltage of sensor can reflect the changes of mechanical angular acceleration according to the experiment. The errors of sensor on actual working condition are analysed, and a new calibration method of sensor is presented, which affords technical support for the popularization and application of sensor.
