  1. Vor 3 Stunden · Zhang et al. proposed the time-varying impact force excitation function of the defective rolling element. In summary, this paper further establishes a dynamic model for the outer race of rolling bearings considering time-varying excitation due to contact deformation based on the Hertz contact theory.

  2. Vor 3 Stunden · Abstract. Rolling bearing is a key component in mechanical equipment, so it is important to carry out fault diagnosis effectively. It is a crucial step to demodulate the modulation components caused by faults in the fault diagnosis method of rolling bearings. In this paper, an advanced demodulation method called harmonic modulation spectrum ...

  3. Vor 3 Stunden · Therefore, this paper uses CWTCatGAN, an intelligent fault diagnosis method for rolling bearings, which combines CWT with CatGAN. Firstly, the original vibration signal is converted into a time–frequency image through CWT, and the image is used as the input data of CatGAN. Then, the CatGAN model is trained adversarial to generate fake samples ...
