Ejection Mitigation Using Advanced Glazing. A Status Report, November 1995

摘要

In response to the National Highway Traffic Safety Administration AuthorizationAct of 1991, the agency initiated research programs concerning motor vehicle rollover protection. As part of that research, the agency has constructed a crashworthiness research program to evaluate ways to reduce the number of fatalities due to ejection. The program was expanded from side impact ejections to include ejections from rollover, front, and rear impacts. On July 1, 1994, the agency created a cross-agency research team to expedite the research and analysis of the problem of vehicle ejection out of glazing. This Advance Glazing Research Team has developed analytical and research tools to evaluate the problem of ejection, and to measure potential mitigating designs. The team has initiated a multi-prolonged approach on analyzing advance glazing. The following activities have been conducted: Developed and built an impactor that can project 18kg (40 pounds) at 24 kmph (15 MPH); Developed full-vehicle computer models and finite element material models (FEA); Monitored technological developments; Manufactured and tested prototype encapsulated windows, mounted into modified doors; Conducted a cost-and-lead time analysis; Conducted a benefit analysis. These issues will be discussed in more detail later in the report.
