HVE Simulation

The accident occurred when a car attempted to traverse a rough railroad track crossing. The driver lost control and veered leftward into a ditch. Vehicle response to the roughness of the pavement was the issue under investigation.

Hydroplaning Analysis

An experimental program was initiated to examine the phenomenon of tire hydroplaning. A number of such accidents have been analyzed by Metz Engineering and Racing (MER), and a considerable amount of theoretical work has also been performed.

IMSA Race Refueling Accident

During an IMSA race pit stop, the quick-release refueling rig failed to detach from the race car as the driver was waived onto the track and attempted to leave the pits. As the car pulled away, the fueling hose ruptured, spilling gasoline onto the hot exhaust of the car and igniting a conflagration in the car pit area.
