The specifications and integration of two new Mod-elica libraries is presented: The Powertrain Dynam-ics (PTDynamics) and the Engines libraries. The lib-raries enable the simulation and modelling of power-train systems including their fluid dynamic, pollutant emission, mechanical and thermal performances in one simulation environment (Dymola), utilising the object orientated modelling language Modelica. Two variants of the Engines library are presented: a Mean Value variant (MVEL) and a Crank Angle Re-solved variant (CAREL). Both the PTDynamics and Engines libraries make use of a new approach to modelling the mechanics that captures the full MultiBody effects of the Powertrain system without the computational cost of using the standard Modelica MultiBody library. 1

This paper presents a flexible, modular model architecture in Modelica for system modeling and simulation of military ground vehicles. The model platform and implemented interfaces are flexible enough to support virtual prototyping of conventional and hybrid vehicles with various physical architectures such as series, parallel, hydraulic, and plug-in implementations. Several sample model implementations of conventional and concept hybrid military ground vehicles are presented to illustrate the usage and flexibility of the model architecture to support systems engineering activities by maximizing model re-use throughout the product development process from concept assessment and design through testing and verification.
