Southwest Research Institute Releases Vehicle Simulation Software Tool

    SAN ANTONIO--March 4, 2002--Engineers and computer scientists at Southwest Research Institute (SwRI(tm)) have developed a modular simulation tool for automotive designers to assess vehicle fuel economy and performance.
    The Rapid Automotive Performance SimulaTOR for Vehicle System Modeling (RAPTOR(tm) VSM), allows designers to configure a virtual vehicle from a number of component and sub-component models. The component models and their associated data can be changed or added to component library databases.
    In addition, component hardware can be put on a test stand and controlled within the framework of a virtual vehicle whose other components are simulated in RAPTOR.
    "RAPTOR is a product that has been years in the making," said Scott McBroom, manager of Advanced Vehicle Technology at SwRI.
    "It includes all source code in SimuLINK(tm), programmed by engineers with test cell experience. This combination becomes evident in the value, features and utilities, making RAPTOR stand out above the rest," McBroom said. The software preserves data and model integrity, saving time and money for organizations that do large amounts of simulation, he said.
    RAPTOR VSM is comprised of both integration-based or forward-looking models, and derivative or backward-looking models. Backward-looking models emphasize execution speed, while forward-looking models emphasize a higher level of detail and fidelity for hardware-in-the-loop, as well as component and controls development.
    Component libraries contain models that characterize the operational behaviors of subsystems such as engines, torque converters, clutches, pumps, gearboxes, wheels and final drives. Vehicle templates representing powertrain configurations feature a number of two-wheel and four-wheel drive variations, for passenger cars as well as light, medium and heavy duty trucks.
    RAPTOR is available for $50,000. To order, or for more information, contact Scott McBroom, Advanced Vehicle Technology manager, Engine and Vehicle Research Division, at 210/522-3454 or e-mail at smcbroom@swri.org.

    SwRI is an independent, nonprofit, applied research and development organization based in San Antonio, Texas, with more than 2,700 employees and an annual research volume of $319 million.
