ABSTRACT: The objective of this project was to develop and analyze a passive system to protect a cab car engineer from secondary impact injuries that might be experienced due to impact with the cab console. The primary requirement for the system was the ability to compartmentalize and limit the injury indices for a 95th percentile Anthropomorphic Test Device (ATD). A baseline cab console was modified with an airbag and a crushable knee bolster to meet this objective. A computer model of an ATD impacting the cab console was validated using results from component-level tests. The modeling results indicate that the engineer protection system is capable of meeting the performance requirements. Subsequent work is planned to build and test the proposed system.
