"The automotive industry, and manufacturers of heavy machinery including construction, agriculture, mining, and military vehicles can benefit from the application of this model to the design of their equipment," he says.
"Also, human factors researchers and ergonomists can use this model to investigate the effect of head-neck posture on human response, performance, human machine interaction, and injury risk in whole-body vibration."
Rahmatalla's long-term VSR objective is to develop a virtual human capable of reproducing complex human responses to a whole body vibration environment that will help answer questions related to potential injury risks and design modifications.
Rahmatalla conducted the study by having 11 male participants sit in a vehicle simulator where they were subjected to white-noise random vibration and the acceleration data of the head and neck for each was recorded. The recorded motion data was used to calibrate the computer human model.
His colleague in the study was Yang Wang, a student in the UI Graduate College and CCAD graduate research assistant.
