University of Iowa researchers have developed software that enables engineers to accurately predict the role posture plays in transferring the stress of vehicle motion to bones and muscles in the head and neck.
"The goal of this project is to introduce a computerized human model that can be used to predict human motion in response to whole-body vibration when the human takes different head-neck postures," says Iowa professor Salam Rahmatalla.
The current model can be used to drive more sophisticated computer-human models that can predict muscle forces and internal strain and stress between tissues and vertebrae, according to the researchers. The system also could reduce the need for human subjects to test-drive vehicles.
"One major benefit of the current computer-human model is the possibility of using it instead of humans in the design/modification loop of equipment in whole-body vibration," Rahmatalla says.
He notes a wide variety of industry, university, and other research venues will be able to find applications for the technology.
