Performance aspects of real-time capable flexible multibody simulations

, 2017
Virtual prototyping in modern vehicle development relies mainly on detailed and versatile vehicle models, which are usually built up as rigid body models. These models are used in many fields within vehicle development, for example for driver-in-the-loop

Monte Carlo Simulation of Flexible Multibody System with Uncertainties

, 2011
Practical mechanical systems often contain several flexible components and uncertain parameters which makes it hard to predict the system behavior and performance exactly. This research presents the uncertainty analysis of flexible multibody systems with

Zero-emission traction for rail

Railway Engineering Science
Replacing the energy density and convenience of diesel fuel for all forms of fossil fuel-powered trains presents significant challenges. Unlike the traditional evolutions of rail which has largely self-optimised to different fuels and cost structures ...

Development of an innovative framework for the simulation of freight trains longitudinal dynamics

Advances in Mechanical Engineering
This paper presents SIMTRAD or SIMulation of TRAin Dynamics, an innovative framework for simulating longitudinal dynamics of freight trains. The framework integrates detailed sub-models of locomotives, wagons, couplers, and adhesion dynamics inside a ...

Influence of Weighted Gradients in Topology Optimization of Flexible Multibody Systems

This paper deals with a level set-based topology optimization of flexible bodies within flexible multibody systems. The required gradient is provided by an adjoint sensitivity analysis. In this work, a modified Solid Isotropic Material with Penalization (
