Computational Modelling of the Rail Vehicle Multibody System Including Flexible Bodies

open access: yesCommunications, 2015
Tools for computer simulations are widely used in the field of a rail vehicle design. These means of virtual reality allow to perform static analyses of rail vehicle parts and dynamic analyses of a rail vehicle multibody system.

Dynamic simulation of non-penetrating flexible bodies [PDF]

open access: yesProceedings of the 19th annual conference on Computer graphics and interactive techniques, 1992
A model for the dynamic simulation of flexible bodies subject to non-penetration constraints is presented. Flexible bodies are described in terms of global deformations of a rest shape. The dynamical behavior of these bodies that most closely matches the behavior of ideal continuum bodies is derived, and subsumes the results of earl ier Lagrangian ...

An efficient Generalized Geometry Contact algorithm including modal reduction flexible bodies

open access: yesMechanical Engineering Journal, 2017
In the MFBD (Multi-Flexible-Body Dynamics) (RecurDyn, 2017), the contact analysis is very important. To develop the general purpose contact algorithm for rigid and flexible bodies, the Generalized Geometry Contact algorithm, which is called ‘Geo Contact ...

Dynamics of semi-flexible fibres in viscous flow [PDF]

open access: yes, 2007
The dynamics of semi-flexible fibres in shear flow and the effect of flexibility on the swimming speed of helical flagella are investigated. High aspect ratio particles such as carbon and glass fibres are often added as fillers to processed polymers ...

Iterative Coordinate Reduction Algorithm of Flexible Multibody Dynamics Using a Posteriori Eigenvalue Error Estimation

open access: yesApplied Sciences, 2020
Coordinate reduction has been widely used for efficient simulation of flexible multibody dynamics. To achieve the reduction of flexible bodies with reasonable accuracy, the appropriate number of dominant modes used for the reduction process must be ...

Numerical Simulation of an Intramedullary Elastic Nail: Expansion Phase and Load-Bearing Behavior

open access: yesFrontiers in Bioengineering and Biotechnology, 2018
The Marchetti-Vicenzi's nail is an intramedullary device where six curved nails are kept straight by a closing ring in order to allow their insertion into the medullary canal of a long bone; in a following step, these nails stabilize the fracture due to ...
