EDVDB-3D (Engineering Dynamics Vehicle Data Base - 3D)                                                                                                                            

EDVDB-3D is a comprehensive 3-D vehicle database developed by EDC for use with HVE. Every vehicle in the database is complete with all the data necessary to perform complex 3-D reconstructions or simulations. Using EDVDB-3D improves results, increases productivity and saves time.

EDVDB-3D is not merely a list of files, but a true hierarchical database. As such, the user selects vehicles according to Type, Make, Model, Year and Body Style as defined in SAE Paper No. 960897, "Updating the Vehicle Class Categories." Vehicles include passenger cars, pickups, vans, sport-utilities, commercial trucks, dollys and trailers. EDVDB-3D also incorporates a database of different tires selectable according to Type, Manufacturer, Model and Size.

The parameters for each vehicle are acquired by EDC Engineers. A complete 3-D mesh of the interior and exterior is produced using a 3-D digitizer. A typical vehicle contains 3,000+ polygons, not including tires and wheels. Suspension rates are measured for each axle. Weights are obtained using platform scales at each wheel. Stiffness coefficients are obtained from leading industry sources, such as NHTSA. Other parameters, such as tire data, are derived from actual tests performed at Calspan, UMTRI and other research facilities. The source of every parameter is documented. An exhaustive review of each vehicle is performed before adding it to the database.
