Used for pedestrian safety testing, Diversified Technical Systems’ pedestrian headforms (which emulate a human head) embedded data acquisition solution are instrumented with a triaxial accelerometer and miniature SLICE NANO data recorder inside and then launched at a vehicle’s hood and windshield to test for potential injuries that may be sustained by pedestrians.
In a production vehicle that Tula tested, conventional operation yielded what was termed an “objectionable” audible boom at 47 Hz with production calibration. However, under DSF operation all firing patterns resulting in frequencies between 44 Hz and 48 Hz were avoided.
Engineers don’t get credit for simply delivering safe, durable and in many ways fun vehicles that delight customers. This is one root of the frustration that’s been growing within Dearborn’s “Core Ford” engineering groups.
