How do the computed results compare to actual crash tests on real cars?
Results from the program correspond very closely to data collected in actual test crashes. Once we know that the models are reasonably accurate, we can conclude that the computer programs provide some benefits we cannot get from physical testing. Computer can provide more data than the sensors and can compute what is happening in areas of the car that cameras cannot see. Can provide more information than a real crash if there is unexpected damage in a position where few sensors were placed. • Uses of the Crash-analysis Models Are replacing physical crash testing as a design tool for new cars. Crash test used as confirmation and is required by the federal government. Should simulation results replace the physical crash? Differences of opinion. Engineers who work with the crash-analysis programs do not believe that physical crashes will or should be eliminated. Simulation is an implementation of theory. The programs are excellent design tools that enable increases in safety with far less
