• 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).
