The paper presents a model for quasi-static analysis of angular contact ball bearings. This model allows the computation of the load distribution on ball and races contacts as a function of radial and axial inner ring displacements, including the eff

The behavior of the contact surfaces between the gear teeth has a significant influence on the gear service properties. An analytical research concerning this behavior by considering a non Hertzian model was developed. A mathematical model of the sur

An analysis model has been developed to model the nonlinear strain rate dependent deformation of rolling bearing steel stressed in the elastic-plastic domain. The model is developed in the frame of the incremental theory of plasticity by using the vo

A vectorial method has been developed to solve the quasi-static equilibrium in angular contact ball bearings. In the quai-static model the effects induced by the centrifugal forces, gyroscopic moments and misalignments between bearing’s rings were

The fatigue life tests carried out on two groups of ball bearings confirm the positive influence of the compressive residual stresses induced by a previous loading in the elastic-plastic domain. The values of residual stresses are numerically evaluat

Numerical methods have gained momentum among specific engineering problems that must be solved in such a manner that accuracy and speed are the two most important aspects to consider regarding the output. This paper presents a fast, semi-analytical m
