Crack propagation prediction in aluminum friction welded joints

Integrated dual boundary element method – finite element method are applied. As well, the welding procedure simulation and the successive crack propagation evaluation are coupled. For AA 2024-T3 aluminium rolled sheets welded, the forging action of the tool shoulder is enhanced by impos...

Influence of temperature on foam used in motorcycle protective equipment

This paper researches influence of the temperature on a foam, which is used in motorcycle protective equipment. The impact test was carried out on samples, which were cut from the center part of the protector that is suitable to protect shoulder, elbow and knee areas. Its...

Testing of honeycomb sandwich panel with potted insert

This work is focused on the experimental and analytical determination of the load-carrying capability of the inserts potted in the sandwich structure with honeycomb core. The pull-out test of the sandwich structure specimens with two types of inserts were performed and load-carrying cap...

Wave dispersion in fluids saturating periodic scaffolds

We consider acoustic wave propagation in periodic scaffolds perfused by Newtonian or inviscid fluids. To analyze the wave dispersion, two approaches are examined: the periodic homogenization (PH) and the Floquet-Bloch wave decomposition (FB). The dispersion analysis using the FB approach captures...

Multi-body simulation of dog clutch engagement

This paper presents a multi-body simulation model in Adams created for optimization of the dog clutch engagement process, especially minimization of the gearshift time regarding to the shape of dogs. The simulation model was validated using measurements of a prototype dog clutch engagem...

On the Numerical Treatment of Nonlinear Flexible Multibody Systems with the Use of Quasi-Newton Methods

This paper deals with the use of quasi-Newton methods for dynamical simulations of nonlinear flexible multibody systems which are modelled using absolute nodal coordinate formulation (ANCF). Three ANCF beam elements are briefly reminded and implemented. The Newmark integration method for index&#x...

Approaches to Fibre Modelling in the Model of an Experimental Laboratory Mechanical System

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 point-mass model and an absolute nodal coordinate formulation. Experimental measurements&#x...

Application of Multibody Dynamics in the Modelling of a Limited-Slip Differential

The paper is aimed at suitable approaches to the modelling and dynamical analysis of a special class of automotive differentials called limited-slip differentials. The design and function of the differential are briefly introduced and suitable multibody approaches to its modelling are propos...
