Reconstruction of an Actual Vehicle Rollover as a Special Project in an Undergraduate Dynamics CourseThe reconstruction of a vehicle rollover was assigned as a special group project in anundergraduate course in dynamics at _______ University. The students were provided with ascene diagram documenting the path of an actual vehicle rollover. Using the principles learnedin their dynamics course, the students were tasked with determining the translational velocity ofthe vehicle throughout the event, including the pre-trip, trip, and tumbling phases. The projectalso required the students to calculate the yaw rate prior to trip and the roll rate during thetumbling phase of the event. With the translational and rotational velocities along with therelevant geometry of the vehicle, the students were able to determine the trajectories ofhypothetical occupants ejected from the vehicle at different points in time during the rollover andestimate the locations where the occupants would come to rest. The data for this rollover camefrom a test conducted on a rural highway by __________ Corporation. A 1994 NissanPathfinder was towed to highway speed before being released, at which point an automatedsteering controller steered the vehicle through a series of maneuvers that resulted in rollover.The test was documented with on-board instrumentation and off-board high-speed video, whichallowed for direct comparison of the students’ reconstructions of the rollover event with whatactually occurred. This course project gave the students the opportunity to demonstrate that theprinciples taught in their undergraduate dynamics course can be used to effectively andaccurately analyze a real-world event.
