Summary
This study investigates the feasibility of using dynamic crash test metrics as surrogates for the static door crush resistance requirements mandated by Federal Motor Vehicle Safety Standard (FMVSS) No. 214. Currently, FMVSS No. 214 requires vehicles to pass both dynamic tests—moving deformable barrier (MDB) and vehicle-to-pole (VTP)—and a static test where doors must withstand specific force thresholds. The research aimed to determine if dynamic performance measurements could replace the static test without compromising safety, by analyzing whether non-compliance in one test configuration correlates with non-compliance in others. Researchers utilized validated finite element (FE) models of a 2015 Toyota Camry sedan and a 2020 Nissan Rogue SUV. The Camry model was based on existing data, while the Rogue model was developed via reverse engineering. Both models were validated against full-scale test data for MDB, VTP, and static door crush configurations, achieving high correlation scores using the CORA objective rating tool. The experimental design involved creating structural modifications in the FE models to induce minimal non-compliance in one specific test condition (static, MDB, or VTP) and then simulating the vehicle’s response in the other two conditions to assess mutual effects. The results indicated that the three FMVSS No. 214 configurations engage distinct primary load paths. For the sedan, static crush resistance relied on door beams and hinge connections, MDB performance depended on B-pillar strength, and VTP performance was governed by sill and floor components. Consequently, structural modifications causing non-compliance in one sedan test did not result in non-compliance in the other two. The SUV study yielded similar independence, with one exception: MDB non-compliance also resulted in VTP non-compliance, likely due to greater sill overlap in SUVs. When evaluating potential surrogate metrics from dynamic tests—such as accelerometer velocities, deformation data, and rigid pole load cell forces—the study found significant limitations. Because dynamic and static tests engage different structural load paths, dynamic measurements generally failed to predict static compliance. However, rigid pole load cell data showed the highest potential for indicating initial door crush resistance. The study concludes that eliminating the static door crush test in favor of dynamic surrogates is not currently feasible due to the lack of correlation between the structural load paths engaged in static versus dynamic impacts. While dynamic metrics like pole load cell data offer some predictive capability, they do not adequately capture the specific door crush resistance required by the static standard. This finding supports the retention of the static test requirement in FMVSS No. 214 to ensure comprehensive side-impact protection across different structural failure modes.
Key finding
Structural modifications causing non-compliance in one FMVSS No. 214 test configuration generally did not result in non-compliance in the other two due to different main load paths, although MDB non-compliance in the SUV also resulted in pole non-compliance.
