Reverse Engineering Using Portable CMM

SAIC (formerly AMTI Corporation) was tasked to retrofit stock HUMVEE military vehicles with the design, fabrication, and testing of augment communications and tactical equipment interfaces in support of the US military forces deployed to the middle east. The job was complicated by the requirement to use only pre-existing vehicle connection points and geometric features without modification, and further complicated by the lack of any useful dimensional drawings or specifications. AMTI received two complete HUMVEE vehicles from the manufacturer for this project.

After measuring both vehicles in several sections with a portable precision CMM (FARO® arm), BC Engineering and Design developed accurately measured 3-D model files of the entire assembly including interior and exterior features.

Engineering Data Package Virtual Analysis

BC Engineering and Design (BCED) was contracted to model and analyze a series of AEHF SATCOM platforms for various locations throughout the Continental US and at overseas military locations.

SAIC and BCED are working jointly to provide installation design data and analysis for multiple installations.

The platforms were analyzed for static, live, environmental, and seismic loading scenarios for each location, based on known environmental data.

BCED engineers modeled the 2D drawings in ProEngineer CREO 3D software and performed analysis in ANSYS Workbench. Loads were applied for the various environmental scenarios, (wind, snow, and seismic) as applicable.

Advanced Extremely High Frequency (AEHF)

Now a critical element of U.S. national security, military satellite communications delivers vital connectivity to armed forces around the globe, making warfighters safer and more effective.

The Advanced Extremely High Frequency (AEHF) system built by Lockheed Martin and Northrup Grumman, incorporates the older MILSTAR capabilities as well as newer upgrades which provide vastly improved global, survivable, highly secure, protected communications capabilities for strategic command and tactical warfighters operating on ground, sea and air platforms. The system also serves international partners including Canada, the Netherlands and the United Kingdom.
