Determination of Machinery Vibration in Radial Sliding Bearings with Integrated Liquid Dampers | Chapter 11 | New Approaches in Engineering Research Vol. 11

 The use of radial bearings with segments on a self-generated hydrostatic suspension has been substantiated in order to satisfy the requirements for precision positioning of axes and efficiency of stabilisation of shaft oscillations of power-consuming rotary machines. The methods of turbomachine dynamical analysis based on the modelling of the quasistationary processes in lubricating films that balance the harmonic loads on the rotor by redistributing the lubricant flow parameters in the bearing with integrated liquid dampers have been further developed. The complex approach for improving functional properties of turbomachine bearings on the basis of multicriteria optimization of hydraulic tracts parameters and lubrication system operating modes is presented.

Recent Study on Failure Diagnosis and Prognosis of Sliding Bearings | Chapter 2 | Advanced Aspects of Engineering Research Vol. 10

 Sliding bearings are commonly used machine elements whose proper operation is dependent on the availability of many technological systems, and the analysis of the prediction method for sliding bearings receives a lot of attention. High levels of vibration and noise are caused by problems with sliding bearings. The thermal analysis is a critical parameter in the diagnosis and prediction of sliding bearing failure. Vibration spectrum analysis, oil film thickness, and other related parameters are often used in addition to these. It is possible to substantially reduce measurement time while increasing the precision of diagnostic methods by using advanced technologies. A mathematically formalised mode of representation for modelling ambiguity is fuzzy logic. In this paper, a selection of damage in the operation of a sliding bearing is made, and the method for diagnosing these issues is demonstrated. Sliding bearing damage can be detected early using methods that combine multiple diagnostic parameters into one.
