AB  - This paper contains elements of a comprehensive research devoted to the dynamic behavior of radial ball bearings in real working conditions. The general motivation for this topic comes from the requirements for high performance operation of bearings within complex mechanical systems, defined in many industrial branches during the last decades. The discussion of the fundamental postulates of the approach used for analyzing the vibration response of rolling ball bearings in order to select the optimal working conditions is given. The certain simplifications and reductions used for analyzing the radial ball bearings are explained. The developed procedure can be used for research of influence of different damages and variable operation conditions on the rolling bearings dynamics. The detail analyses of the dynamic behavior of rolling bearings are performed for particular types of radial ball bearings in two case studies: For the damaged outer raceway surface in accordance with real fatigue damage shapes and dimensions and, for variable working temperature. Obtained results are shown by comparative diagrams of vibration and phase plane portraits. Presented results could be a base for more widely research of nonlinear dynamics of radial ball bearings with different damages and for the application of phase plane analysis in order to choose the optimal operation conditions.

AB  - Major function of railway vehicles absorbers is to absorb energy through controlled deformation during frontal rail vehicle collisions. The results presented and discussed in this paper is a part of the research of one particular type of absorber consist of a thin-walled seamless tube and conical mandrel. The influence of the groove, which occurred during cold worked tube manufacturing, on the behavior and energy absorption of this type of shock absorber is analyzed. The coupled nonlinear Finite Element Analysis is used for calculation of stress-strain state and plastic deformation work/volume of tube absorbers with defects. The results of the research presented in this paper show that the grooves on outer surface of expansion tubes in some cases can be beneficial due to strain hardening process in root of stress concentrator i.e. defect. The beneficial effect of grooves is proven by simulation in which is obvious that the energy absorbed level could be higher on expansion tube with grooves.

The material non-linear models features in Finite Element Analysis (FEA) are explained with special attention in non-linear kinematic hardening material models.
For simulating of non-linear kinematic hardening and ratcheting effects of AISI 316 steel the Chaboche constitutive material model is used. The Finite Element Model of rectangular block modeled for material behavior simulation is shown. Definition of constraints and input stresses is explained in detail.
The results obtained after six cycles of input stresses give the excellent superposition with theoretical results of other authors. The created diagrams show the ratcheting phenomenon of research material. Therefore, the FEM model developed for non-linear kinematic hardening research is verified and could be used for wide research of different materials under different input loads.

AB  - The research of influence of operation temperature on the thermal expansion and main parameters of radial ball bearings is presented in this paper. The main bearing parameters are identified in accordance with the increasing requests concerning stability and load capacity. A series of finite element analyses is performed for quasi-static analysis of all identified bearing parameters during contact period in referent temperature. Then, the dependence of bearing material characteristics on the operation temperature is discussed. Few series of finite element analyses are performed for a particular radial ball bearing type, with characteristics in accordance with manufacturer specifications, for several operation temperatures. These two problems analyses include consideration of relation between the initial radial clearance, thermal expansion strains, and contact deformations of the parts of the bearing assembly. The results for radial ball bearing parameters are monitored during a ball contact period for different temperatures and the appropriate discussion and conclusions are given. The conclusions about the contribution of developed procedure in defining the optimum operation temperature range are shown.

abstract = "The research of influence of operation temperature on the thermal expansion and main parameters of radial ball bearings is presented in this paper. The main bearing parameters are identified in accordance with the increasing requests concerning stability and load capacity. A series of finite element analyses is performed for quasi-static analysis of all identified bearing parameters during contact period in referent temperature. Then, the dependence of bearing material characteristics on the operation temperature is discussed. Few series of finite element analyses are performed for a particular radial ball bearing type, with characteristics in accordance with manufacturer specifications, for several operation temperatures. These two problems analyses include consideration of relation between the initial radial clearance, thermal expansion strains, and contact deformations of the parts of the bearing assembly. The results for radial ball bearing parameters are monitored during a ball contact period for different temperatures and the appropriate discussion and conclusions are given. The conclusions about the contribution of developed procedure in defining the optimum operation temperature range are shown.",

AB  - This paper describes the influence of corrosion on stress concentration factor and crack initiation at shaft-flange transition section. The real turbine shaft failure case study is used for research. This case study and numerical calculations show that the seal box solution led to constant leakage of river water in the zone of critical radius and resulted in corrosion fatigue cracks and turbine shaft failure. Thus, the Finite Element Analysis is performed to calculate the stress concentration factor increase as a result of corrosion occurrence. The corrosion at shaft-flange transition section is modelled in the zone with maximum stresses with a corrosion pit dimensioned to comply with real in situ dimension of pits. The presented research points new trends in stress concentration factor calculation. The obtained numerical results for maximum stress and stress concentration factor in critical zone confirmed failure analysis study outcome.

AB  - This paper describes the analysis of major failure of 28 MW horizontal hydro turbine shaft. The analysis of load carrying capacity of critical radius and fractography analysis are presented. Special emphasize is on metallurgical failure analysis of in-service crack initiation. The analysis of stresses is obtained by the finite element method and the developed model and load conditions are described. Finite element analysis is performed for case of normal service and start-up regime. Based on the failure analysis and numerical calculations, it could be concluded that the seal box design led to constant flow of river water in zone of critical radius which resulted as occurrence of corrosion fatigue cracks and major failure of turbine shaft. Suggestions for problem solution for the turbine shaft are also presented.

AB  - This paper displays the usage of Theory of Critical Distances (TCD) in the prediction of high-cycle fatigue behaviour in machine parts and systems. It is possible to gain real overview of stresses of machine parts by Finite Element Analysis, and to use them as an entry values for application of Theory of Critical Distances. The TCD represents a major extension of linear elastic fracture mechanics, allowing it to be used for short cracks as well as for stress concentrations of arbitrary geometry. Presented methodology is particular valid for machine parts of non-standard dimensions. A particular turbine shaft from hydro power plant was chosen as subject for developed methodology presentation. This paper illustrates the application of the TCD on decrease of fatigue life of turbine shaft due to shaft-flange radii stress concentration and corrosion pits.

As a result of thermal fatigue, dilatation of steam pipe line at an operating temperature may lead to cracks initiation at the critical zones within heat affected zone of steam pipe line welded joints.
