Vehicle Characterization tests were performed on two of three commercial span bolsters cars (Triplet Cars) to gather data in support of the Train Dynamics Model (TDM) prediction of coupled span bolster car performance and results are included in the report. The three vehicle characterization tests were: (1) static suspension characterization, (2) quasi-static suspension characterization, and (3) modal response testing. Modal testing was performed to assess any resonant rigid or flexible body modes that may be encountered during track testing. Quasi-static truck characterization tests were performed to characterize the vehicle suspension for input to the TDM. Static suspension characterization tests consisted of four subsets of air bearing table tests. They were: span bolster yaw moment, truck yaw moment, longitudinal stiffness, and axle yaw stiffness. Air bearing table test data appeared to be useable for TDM development.
