EDVDS

EDVDS (Engineering Dynamics Vehicle Dynamics Simulator) is a 3D simulation of the response of a commercial vehicle (tractor towing up to three trailers) to driver inputs (steering, braking and throttle). EDVDS incorporates a powrful, new tire-terrain interaction model, allowing a vehicle to be simulated on virtually any surface. The program computes vehicle kinetics (position./velocity/acceleration vs. time), tire-forces and moments, suspension forces and deflections, drive and brake systems.

EDVDS is useful for prdicting and visualizing how a vehicle-trailer system responds to driver inouts, especially for limit maneuvers resulting in loss of control followed by jackknife or rollover. EDVDS has been validated against several well-instrumented vehicle handling studies, including steering and braking, severe irregular terrain traversal, and roll-over tests involving curbs and soft soil.
