The Method of the Abnormal Sound Detection for Final Drive Based on DSP Technology

Abstract:

According to the mechanism of the main reducer abnormal sound signal is different from the interfering noise, a detection method based on the digital signal processing technology was proposed. With the qualified main reducer noise signal as the reduction sample, the detected main reducer noise signal is de-noising by means of spectrum analysis, and then be estimated whether the detected main reducer is qualified based on certain threshold values. Finally, the detection method is validated, which provided a new thought on the final drive abnormal sound on-line detection.
