Abstract
Each year, hundreds of people die as a result of agricultural tractor rollovers. The National Institute for Occupational Safety and Health (NIOSH) within the U.S. Department of Health and Human Services is charged with conducting research to ensure the safety of America's workers and to help prevent such deaths. Engineers from the NIOSH Division of Safety Research (DSR) are studying tractor rollovers and attempting to solve an old problem through application of new technologies. NIOSH researchers are using ANSYS software to simulate tractor rollover dynamics and to study the structural response of the rollover protective structure (ROPS), or rollbar, during a rollover. Such analyses allow researchers to study rollover mechanics via computer and have the potential to reduce the number of field tests required. In addition to studying the structural response of the roll bar, researchers are interested in understanding the conditions precipitating rollover and want to use this information to design new safety controls or improve older technology.
