3D projection of the LuGre friction model adapted to varying normal forces

In this paper, we develop an adaptation of the LuGre friction model so as to allow the development of the friction force and its application in any directions on systems subjected to varying normal forces. This is achieved by projecting a modified LuGre model adapted to&#...

Modelling of dynamic behaviour of fibres and cables

In this paper there are presented some possible approaches suitable for the modelling of the fibre and cable dynamics in the framework of various mechanical systems: force representation of a fibre, a pointmass model and an absolute nodal coordinate formulation. Experimental measurements...

Comparison of implicit time-discretization schemes for hybridized discontinuous Galerkin methods

The present study is focused on the application of two families of implicit time-integration schemes for general time-dependent balance laws of convection-diffusion-reaction type discretized by a hybridized discontinuous Galerkin method in space, namely backward differentiation formulas (BDF) and diagonall...

Komplexní výpočtové modelování kluzných ložisek s naklápěcími segmenty

Tilting pad bearings can be found in rotating machinery with high circumferential speeds of journals. Vibrations of individual pads are usually neglected in rotordynamics simulations and hydrodynamic forces acting in oil films are often linearized. A computational model which respect...

Experimental and computational study on mechanical stabilisation of sacral bone injuries

The experimental study focuses on minimally invasive fixation techniques of linear sacral fractures and its results are utilised for development and validation of the related computational model. The model is extended for analysis of unstable pelvic ring injuries with spinopelvic dissociation...
