Pantograph catenary dynamic optimisation based on advanced multibody and finite element co-simulation tools [PDF]
This paper presents recent developments undertaken by the SNCF Innovation & Research Department on numerical modelling of pantograph catenary interaction. It aims at describing an efficient co-simulation process between finite element (FE) and multibody (

Multibody dynamics modeling of electromagnetic direct-drive vehicle robot driver
Collaborative dynamics modeling of flexible multibody and rigid multibody for an electromagnetic direct-drive vehicle robot driver is proposed in the article. First, spatial dynamic equations of the direct-drive vehicle robot driver are obtained based on

N ordsieck form of multirate integration method for flexible multibody dynamic analysis
A Nordsieck form of multirate integration scheme has been proposed for flexible multibody dynamic systems of which motions are represented by large gross motion coupled with small vibration.

Port-Hamiltonian flexible multibody dynamics [PDF]
A new formulation for the modular construction of flexible multibody systems is presented. By rearranging the equations for a flexible floating body and introducing the appropriate canonical momenta, the model is recast into a coupled system of ordinary ...

Hierarchical refinement in isogeometric analysis for flexible multibody impact simulations
Detailed impact simulations in flexible multibody systems can be simulated based on reduced isogeometric analysis (IGA) models. However, a precise simulation of an impact requires a high element resolution in the contact area.

Advanced modelling of flexible multibody systems using virtual bodies
When new formulations for the description of flexible multibody systems are proposed, often they imply the use of new sets of generalized coordinates, even if the finite element method is used to describe the system flexibility.

The longitudinal drawbar and the lateral stabilizer bar of straddle-type monorail vehicle with the single-axle bogies have relatively long structure size. The multibar system leads to deformation during the driving process due to impact loads, even leads

Formulation of flexible multibody systems.
This paper deals with equations of motion of a flexible multibody system whose bodies are connected by rotational hinges. The equations of motion are derived by taking degrees of freedom of one body properly set in the system, hinge rotational angles, and modal coordinates of flexible bodies as independent variables. Kane's equations of motion are used

Modular Modelling of Flexible Thin Beams in Multibody Systems [PDF]
In this paper the problem of modelling flexible thin beams in multibody systems is tackled. The proposed model, implemented with the object-oriented physical systems modelling language Modelica, is completely modular, allowing the realization of complex systems by simple aggregation of basic components.

End-effector trajectory tracking of flexible link parallel robots using servo constraints
We apply the concept of servo constraints to end-effector trajectory tracking control of parallel robots with structural link flexibilities. Such servo constraints deliver the inverse robot model where solution approaches via projections are proposed ...
