“…However, based on the results of vibration analysis, it can be concluded that the dominant vibration values were obtained in medium frequency band from 300 to 1800Hz. This may indicate excessive values of raceways waviness deviation (Adamczak, 2017a). Analyzing the results presented in Figure 3 it can be concluded that the increase the values of radial clearance causes an increase in the values of vibration level analysed in medium and high frequency band (see Fig.…”

“…The natural frequencies of investigated bearings were as follows: frequency from rotation: 30 Hz, frequency from outer ring: 77.,22 Hz, frequency from inner ring: 132.78 Hz, frequency from balls: 105.45 Hz. The first step of research procedure was measurement of vibration velocity using measuring device known as Anderometer (Adamczak, 2017a). The examined bearings were mounted on spindle.…”

The paper presents research of the influence of the radial internal clearance of the rolling ball bearings on the basic exploitation parameter which is the level of vibration. The measuring method of radial internal clearance of rolling bearings and measuring device are described. The 6304 type ball rolling bearings were used in research. The experimental research consisted of measurements of radial internal clearance and vibration level. The vibration analysis was divided into three basic frequency bands: low (50-300 Hz), medium (300-1800 Hz) and high (1800-10 000 Hz). The research was carried out in Laboratory of Rolling-Elements Bearings located in Kielce University of Technology. The research results showed that the increase of the radial clearance values affect the level of vibration generated by rolling bearings. The biggest influence was noted in the medium vibration frequency band.

“…The RMS tested in these bands is typical for the control of newly manufactured rolling bearings. These bands are of course closely related with the rotational speed applied [12][13][14]. Each of the three bands has different supposed defects.…”

Using of laser vibrometers in vibration measurement systems brings additional benefits due to the lack of impact of the sensor on the tested measuring system. Recently, leading rolling bearing manufacturers are equipping their diagnostic measuring systems with non-contact sensors. Doppler laser vibrometers are used interchangeably for electrodynamic sensors. This paper attempts to assess the vibrometer in use for measuring vibration of rolling bearings in industrial conditions.

“…Among them, the waviness error will affect the use of mechanical parts, so the impact of surface waviness has caused many scholars to study this in depth. Adamczak et al [3] found that an increase in the surface waviness on the inner and outer raceways causes an increase in the vibration level. This effect is most visible for the medium vibration frequency range.…”

Potassium dihydrogen phosphate crystals exhibit excellent nonlinear optical properties that are significantly affected by the surface morphology of the crystal. To comprehensively examine and characterize the morphological features of these crystals, the machined surfaces of workpieces are analyzed using wavelet, fractal, and power spectral density (PSD) methods. First, the fractal method is employed to analyze the features of the machined surfaces of different materials and examine the relationship between the surface roughness and fractal dimension of different materials. Then, the morphological anisotropy of the machined surfaces is analyzed using the two-dimensional PSD method. Based on the orientation of the machined surfaces of the workpieces, the tangential waves on the surfaces are analyzed using wavelet-transform and PSD methods. From a frequency-domain perspective, the scales of various influencing factor signals are identified. Additionally, the frequency range of the spindle vibration is determined based on the machining experiment. On this basis, the cause of the machined surface waviness errors is revealed.
