EDSMAC

EDSMAC (Engineering Dynamics Simulation Model of Automobile Collisions) is a simulation of single- and two-vehicle accidents, including collision. EDSMAC incorporates a powerful, new tire-terrain interaction model that allows vehicle motion to be simulated on 3D surfaces. EDSMAC computes collision and tire forces at user-specified timesteps. The program then display the results visually in a 3D viewer and numerically in the form of vehicle kinetics (position/velocity/acceleration vs. time), tire forces and driver inputs (throttle, braking and steering).

EDSMAC may be used to predict and visualize how vehicles respond during impact. EDSMAC has been validated using the RICSAC collision experiments, a set of 12 well-instrumenhted staged collisions. Several validation studies have been published in the technical literature.
