Abstract Details

2011, Master of Science, Ohio State University, Mechanical Engineering.
Data obtained by the Consumer Product Safety Commission (CPSC) has led to increased concerns regarding the safety of recreational off-highway vehicles (ROVs). As ROVs are a relatively new class of vehicle, meaningful tools for the evaluation of the effects and performance of occupant protection structures (OPS) and roll-over protection structures (ROPS) have not yet been established. In order to provide a system for the examination of occupant kinematics and the effectiveness of OPS, SEA Limited has developed and built the Roll Simulator. An initial validation of the Roll Simulator has been accomplished based on vehicle dynamics; however, evaluation of occupant kinematics requires the implementation of a suitable occupant response tracking system. This work examines the suitability of two non-contact systems, video capture and a three-dimensional optical motion capture system (OMCS), and compares these systems to a string potentiometer system which provides a baseline measurement. Additionally, a preliminary comparison of occupant responses generated by the Roll Simulator to occupant responses obtained through autonomous roll testing is presented. An inertia measuring unit (IMU) based tracking methodology is considered, but ultimately abandoned due to equipment short comings. Both the video system and the OMCS are found to provide adequate accuracy in tracking kinematic response of the ATD. Characteristics which define the suitability of these systems are presented. The Roll Simulator is found to reproduce vehicle and occupant responses from real-world autonomous testing with a high level of agreement.
