Modelling of suspension components in a rail vehicle dynamics context

TLDR

There are 4 labels present. Let's parse: Background lines: - [Background] "Abstract Suspension components play key roles in the running behaviour of rail vehicles, and therefore, mathematical models of suspension components are essential ingredients of railway vehicle multi-body models." - [Background] "DynoTrain is a collaborative project – medium-scale focused research project supported by the European 7th Framework Programme, contract number: 234079." So background: combine: suspension components essential for running behaviour; models essential; DynoTrain project context. Purpose lines: - [Purpose, Mechanism] "The aims of this paper are to review existing models for railway vehicle suspension components and their use for railway vehicle dynamics multi-body simulations, to describe how model parameters can be defined and to discuss the required level of detail of component models in view of the accuracy expected from the overall simulation model." - [Purpose, Mechanism] "This paper also addresses track models in use for railway vehicle dynamics simulations, recognising their relevance as an indispensable component of the system simulation model." So purpose: review existing models for suspension components and track models, describe parameter definition, discuss detail level for accuracy. Mechanism lines: - [Purpose, Mechanism] same as above (already counted) - [Purpose, Mechanism] same as above - [Mechanism] "Finally, this paper reviews methods presently in use for the checking and validation of the simulation model." So mechanism: review methods for checking and validation of simulation model; also includes review of models and track models?

Abstract

Abstract Suspension components play key roles in the running behaviour of rail vehicles, and therefore, mathematical models of suspension components are essential ingredients of railway vehicle multi-body models. The aims of this paper are to review existing models for railway vehicle suspension components and their use for railway vehicle dynamics multi-body simulations, to describe how model parameters can be defined and to discuss the required level of detail of component models in view of the accuracy expected from the overall simulation model. This paper also addresses track models in use for railway vehicle dynamics simulations, recognising their relevance as an indispensable component of the system simulation model. Finally, this paper reviews methods presently in use for the checking and validation of the simulation model.
