Engineering Dynamics Corporation Introduces "EDHIS", a New 3-D Occupant and Pedestrian Simulator for Vehicle Safety Research

The Company Leverages Its HVE Technology To Produce The Industry's First Quick And Easy-To-Use Human Occupant and Pedestrian Simulator

BEAVERTON, OR — October 10, 1996 — Engineering Dynamics Corporation, the world's leading developer of motor vehicle accident reconstruction and simulation software, has introduced EDHIS (Engineering Dynamics Human Impact Simulator), the first HVE-compatible human occupant and pedestrian simulator with integrated 3-D visualization.

Safety researchers are reconstructing motor vehicle crashes to help create a safer environment for the motoring public. Using EDHIS, researchers from government agencies, private research institutes, insurance companies and vehicle manufacturers can scientifically visualize how occupants and pedestrians are injured during crashes. Originally developed for the study of advanced restraint system technologies, EDHIS also has the ability to predict injury mechanisms. Researchers use this information to help design safer vehicle interiors and restraint systems.

EDHIS offers greater speed, allowing researchers to set up and execute human occupant and pedestrian simulations more quickly and easily than existing simulation programs. The data requirements, which pose a barrier in existing programs, are greatly reduced because EDHIS is HVE-compatible.

"Now accident researchers can study occupant injuries in every case," said Terry D. Day, president of Engineering Dynamics Corporation. "The benefits are obvious. Currently, fewer than one in 200 serious crashes is studied using human simulation. By using EDHIS, we can increase our sample size by more than two orders of magnitude. The increased volume of new information will greatly improve our understanding of how crash injuries occur." In addition, Day says the ability to illustrate the effect of non-use or incorrect use of restraint systems will be very educational.

For years, safety researchers have focused on reconstructing the collision between the vehicles, then inferring how injuries occurred. Using EDHIS, researchers can focus directly on their primary goal, how the injuries actually occurred.

Engineering Dynamics Corporation, with headquarters in Beaverton, Oregon, developed and marketed the first professional software tools for motor vehicle safety researchers in the early 1980's and now has over 1500 customers in 27 countries.
