NVision Scanner Ensures Accuracy of Crash Dummies Used to Check Rollover Performance |
The need for scanning arose when a mathematical formula was developed to define the geometry of a dummy, which, like many others, was originally based on a physical mold. “Crash dummies have been developed over the years largely as physical molds,” said FTSS Engineer Steve Goldner. “The geometry of the dummy has a major impact on crash test results but it has become essential to convert the original designs to mathematical models in order to enable improvements in manufacturing technology. It also helps avoid damage to the original mold.” FTSS engineers designed a new dummy based on the mathematical model. Since physical measurement methods could not provide the level of accuracy needed to confirm that the new design matched dummies built from the original mold, they used laser scanning to measure the new dummy. FTSS selected the NVision HandHeld scanner for this task because of its wide-stripe laser, speed, accuracy, and ease of use. The scan data is quickly converted to an STL file, which can be easily compared to a computer aided design (CAD) model. They used this process to fine-tune the mathematical formulae until they were able to create a new dummy and confirm it exactly reproduced the original mold designs. To date, FTSS has reverse-engineered between 30 and 40 dummies with the NVision HandHeld scanner. This process ensures that current test dummies are consistent with those used in the past, which in turn ensures the accuracy of the crash tests that are used to evaluate automobile safety.

You scanned a couple of boat propellers for us awhile back. I am happy to say it has helped us in improving our performance and we have set a new world record and a speed that exceeded any drag boat speed in history by 10 + MPH.
