Development of Crash Energy Management Performance Requirements for Light-Rail Vehicles

The primary objective of this research is to provide technical assistance to enable the ASME RT-1 Committee and its CEM Subcommittee to determine reasonable performance requirements for dynamic crush behavior for LRV-to-LRV collisions based on a CEM approach that minimizes the probability of injury and fatality for a range of LRV designs under various high-risk collision scenarios. As a secondary objective, the ASME RT-1 Committee and its CEM Subcommittee seek information and guidance on the technical feasibility and practicality of CEM zones to mitigate damage and human injury in roadway vehicles during LRV-roadway vehicle collisions. This research will support the current ASME RT-1 effort to develop an ASME structural safety standard for LRVs. The research should determine through engineering analyses (e.g., computer simulations) the relationships between crush behavior and the risk of occupant injury and fatality over a range of possible LRV designs and LRV-to-LRV collision scenarios. Suggestions should be provided for defining vehicle dynamic strength requirements. The research should use non-linear, dynamic computer modeling to estimate the LRV-to-LRV crush behavior and the buff strength of several current LRV designs to assist in understanding the implications of considering a change in design requirements from static strength to CEM. It is not anticipated that computer simulation validation tests will be required for any part of this research; however, existing results of relevant tests previously performed by others may be considered. In addition, it is not anticipated that detailed computer simulations will be required for the secondary objective regarding LRV-roadway vehicle collisions. Rather, it is desired that guidance in this area can be developed based on available information and less-rigorous technical analyses.
