Abstract In support of Department of Defense (DOD) mandated acquisition reform initiatives to reduce vehicle related life cycle costs and timelines, the Tank-automotive and Armaments Research, Development and Engineering Center (TARDEC) is using simulation-based acquisition strategies to investigate the dynamic performance of wheeled and tracked ground vehicles. These strategies are used throughout the vehicle development, testing, and fielding life cycle process. The paper will describe how modeling and simulation (M&S) is applied to answer a wide variety of design and performance evaluation questions. It will also depict a series of simulation-based engineering projects that build on the Army’s simulation investments as a tool to investigate and answer real-world vehicle design, acquisition, and engineering support questions.

This paper describes how modeling and simulation tools are being developed and used to support the design of hybrid electric drive (HED) for future military ground vehicles. The component and controls models described are being developed in a modular form such that they can be used to construct subsystem level models of various proposed HED architectures with a consistent, high level of fidelity. The objective models must predict system performance adequately to support the making of engineering design decisions concerning architecture, control algorithms and component sizing. A brief introduction to the challenges associated with the design of a hybrid electric drive for future military ground vehicles is provided.
