The dynamic behavior of the fast rotating system in dependence on operating parameters of bearing supports

Typical components of many industrial devices are rotating parts. In case of automotive engines, turbochargers are used in order to increase the engine efficiency. These turbochargers are understood as relatively small rotating parts working in aggressive conditions. Although they are usually...

Identification of material parameters using homogenization approach and SfePy software

The finite element solver SfePy and Python modules are used to identify the material parameters of the carbon fibers and the epoxy matrix which constitute a unidirectional long-fiber composite. The mathematical model of the heterogeneous structure is base on two-scale homogenization method&#...

Vortex induced vibration of 1D beam-type continua

The contribution focuses on the modelling of vibration of 1D beam-type continua induced by cross flow of a fluid. The influence of fluid flow is represented by the harmonic force whose frequency depends on the Strouhal number. Based on the widely used FEM formulation, vector&#...
