Article Synopsis
- * The article proposes an improved approach using advanced signal processing techniques, including audio preprocessing algorithms and the extraction of damage index vectors with cumulative energy entropy and mel frequency cepstrum coefficients.
- * Experimental results show that the new method achieves a high detection accuracy of 90% to 96.7% for identifying bolt looseness across various torque levels, demonstrating its effectiveness.
