Abstract
A generic framework for designing large, complicated systems is formulated, implemented, and used in the design of mechanical systems, including a pressure vessel, an automotive hybrid powertrain, and a tracked vehicle. The framework supports simulation-based design, distributed and heterogeneous computing resources, custom and legacy simulation and analysis codes, reconfigurability of the design problem, and security of operation across untrusted networks. The framework also facilitates the implementation of methodologies for system design that employ design model partitioning and coordination, as well as a variety of models and search algorithms. Common Object Request Broker Architecture (CORBA) middleware for distributed, object-oriented applications was selected to develop and implement the framework. Framework components include subsystem model, design model, search engine, design model partitioning, design coordination, and user interface.
