The purpose of this study is to track harmonic and resonance components in rotating machinery simultaneously using Vold-Kalman Filter. Experimental study was also performed using a rotating machinery in order to verify that this order tracking means was able to decouple close and crossing order such as harmonic and resonance components in a rotating machinery. Displacement response was measured while rotational frequency was sweeped over its natural frequency. Frequencies and amplitudes were estimated from this response data with Kalman Filter and Vold-Kalman Filter. In this experiment, this order tracking method was verified to capable of decoupling and tracking simultaneously harmonic and resonance components in a rotating machinery.
