  • Abstract:
    Previously, Sharma & Associates, Inc. (SA) developed a higher speed freight truck design under sponsorship of the Federal ; Railroad Administration. Under the current contract, SA was tasked with developing performance requirements for higher speed ; freight trucks, as well as conducting structural and dynamics simulations in accordance with the performance specifications ; developed in the earlier task components of this project. This report presents the vehicle dynamics analyses of the truck. These ; analyses follow the performance requirements laid out for this project in a report titled “WBS TASK 1.1, Higher Speed Freight ; Truck – Performance Requirements.” The requirements were based on the approach presented in FRA’s Notice of Proposed ; Rulemaking (NPRM) on Vehicle/Track Interaction Safety Standards; High-Speed and High Cant Deficiency Operations published ; on May 10, 2010. The vehicle dynamics simulations were conducted at speeds between 95 to 130 mph in 5 mph increments on ; Class 7 track, as well as for 115 mph on a Class 6 track. The simulations showed that the higher speed freight truck meets all ; previously specified performance criteria. Based on the results discussed in this report, it is recommended that a set of field tests ; be carried out to evaluate and validate the higher speed freight truck’s performance under Chapter 11 regimes. Further tests ; should be run at speeds 100 mph or higher at a facility such as Transportation Technology Center, Inc. (TTCI).
