• Abstract:
  Non-linear large deformation analyses have been conducted ; to evaluate the performance of the cab car corner and collision ; posts of the Federal Railroad Administration's (FRA) ; sponsored state-of-the-art (SOA) end frame design and the ; Bombardier M7 design under quasi-static and dynamic test ; conditions. Pre-test analysis predictions of the dynamic ; performance of the SOA corner post closely match test ; measurements. A similar analysis of the corner post was ; performed on the M7 design, and the results compared with the ; SOA test and analysis results. Using this M7 model, analysis ; results for the quasi-static test of the collision post were ; developed, and compared with the test measurements. Up to ; the onset of material failure, the analysis results and test ; measurements closely agree. After the onset of material failure, ; the results progressively diverge. Overall, the crashworthiness ; performance of the collision posts of the SOA and M7 designs ; were found to be essentially the same, and the performance of ; the M7 corner post design was found to perform better than the ; SOA corner post design. This difference in performance comes ; from the sidewall support in the M7 design, which is not ; present in the SOA design.
