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  - The main performance of involute gears operation leads to the appearance of nonlinear dynamic behavior and impact. In this chapter the influence of mild wear of the tooth flanks of gears without machine finishing and surface hardening on the vibro-impact behavior is considered. For this purpose, a new theoretical model for vibro-impact dynamics of spur gears with mild wear on tooth flanks is developed and described. The developed theoretical model is based on the main postulates of a model of the central centric collision of two fictive rolling disks with radii equal to the radii of kinematic diameters of the pinion and the wheel, as well as on a combined analytical/numerical approach used finite element analysis for the calculation of contact deformations, contact pressure, and wear on tooth flanks surfaces. A particular gear pair for earth moving machine is used for presenting the developed model. The conclusions about the influence of mild wear on the vibroimpact oscillations during running-in period are described.

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.

AB  - The consideration of the optimal design of the transition zone of turbine shaft to flange has a high impact within the turbines design. The main principles of biomimetics give a new and prosperous point of view on the machine design, and could recommend a new options in the design solutions for the zones with high stress concentrations. In this paper, a particular turbine shaft with flange is used for research of the possible biomimetics solutions in the zone of the transition radius. The traditional design of this transition zone is compare with the new design option inspired with transition zones in nature. The presented turbine shaft to flange design by biomimetics principles are based on the design of transition zones on trees. The Finite Element Analysis is performed for the traditional designed transition zone, as well as for the transition zone with design based on the biomimetics. The comparative analysis of the obtained results lead to the conclusions about the advantages of the biomimetics approach in this area of machine design.

AB  - This paper presents the new approach for solving the non-linear dynamics of complex mechanical systems, which contains two or more deformable bodies in contact. The developing of presented approach is motivated by problems of solving the vibrations and noise generated by real complex mechanical systems. The analyzed problem is characterized with continuous changes of contact areas' geometry, friction, load distribution and other parameters. Therefore, the problem of non-linear dynamics of mechanical systems with contact pairs becomes very complex. The wide experience in different real problems of analyzed type and experimental verification of the obtained results were the basis for new approach and procedure developing.
The comprehensive and unique procedure for solving the dynamics of mechanical systems with deformable bodies in contact presented with appropriate algorithm gives the simplified framework for analysis of all mechanical systems of this type. However, a very high level of comprehensions of real mechanical problems is required for successfully application of the described approach. Also, the high knowledge about different analytical and numerical methods for solving the tasks included in the particular procedure is necessary.

The special attention is paid to the developing of model for precise simulation of spur gear teeth contact by finite element method (FEM). The contact stress calculation based on true contact involute geometry provides the stress gradients for theory of critical distances (TCD) application in damage initiation prediction. One particular spur gear pair is analysed for presenting the spur gear model developing.

AB  - The coupled non-linear transient calculation is performed and explained in order to simulate the kinematic hardening behavior of AISI 316 steel and the Finite Element Method (FEM) is used for presented simulation. 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.
