In this study, the occupant containment characteristics of automotive laminated safety glass in side window applications was evaluated through two full-scale, full-vehicle dolly rollover crash tests. The dolly rollover crash tests were performed on sport utility vehicles equipped with heat-strengthened laminated safety glass in the side windows in order to: (1) evaluate the capacity of laminated side window safety glass to contain unrestrained occupants during rollover, (2) analyze the kinematics associated with unrestrained occupants during glazing interaction and ejection, and (3) to identify laminated side window safety glass failure modes. Dolly rollovers were performed on a 1998 Ford Expedition and a 2004 Volvo XC90 at a nominal speed of 43 mph, with unbelted Hybrid II Anthropomorphic Test Devices (ATDs) positioned in the outboard seating positions.

Screening experiments were run with the HVE simulation software by Engineering Dynamics Corporation to identify a roadside police vehicle orientation that is more effective than current practices at protecting the extravehicular police officer from being struck by an errant passing vehicle as the officer makes contact with the driver of a suspect vehicle. The most common roadside police vehicle orientations used by police officers were modeled in the simulation to identify adjustable factors and practical level settings for the factors to be utilized in the screening Design of Experiments. Subsequently, the main effects were evaluated, a recommended vehicle orientation was identified and optimized using the simulation and a practical procedure for orienting the police vehicle in the recommended position was developed. Finally, a crash test was conducted to confirm the study methodology.
