General Motors is advancing the state of the art in testing of rear-seat crash test dummies. One of its crash-test engineers, Barbara Bunn, recently developed and conducted tests to evaluate the ability of a new dummy named BioRID to produce consistent measurements when subjected to identical tests. The United States Council for Automotive Research has recognized Bunn for her execution of the test matrix. To create the test matrix, Bunn, who chairs the Occupant Safety Research Partnership’s Rear Impact Dummy Task Group, collaborated with engineers from Chrysler, Ford, and Humanetics Innovative Systems, which manufactures the BioRID. She designed the construction of a crash simulator sled to simultaneously test four BioRIDs, working with engineers from Porsche, Volkswagen, Daimler, Chrysler, and Ford to determine seating postures and other test criteria. The tests subjected the dummies to a low-speed rear impact simulation in nearly identical seats, and collected measurements of crash forces on areas such as the upper and lower neck. The team compared its measurements to data from similar tests conducted by other automaker labs in Europe and submitted its findings to regulators worldwide for consideration.
