Future NUCARS® Developments

Transportation Technology Center, Inc (TTCI®) continues to develop the NUCARS® software, to support TTCI's on-going research and development for the Association of American Railroads (AAR) and worldwide railroad industry customers. This was recently demonstrated in the release of a comprehensive multi-body track model within NUCARS®, and the computation of wheel/rail contact geometry in real time. Current development efforts are focused on the inclusion of more non-linear suspension elements commonly used in the railway industry, and improving the user interface. The following are a few of the major items that are currently in the works.


IMPROVED SIMULATION of FRICTION WEDGES

  • Research partnership under AAR affiliated labs program
  • True stick-slip for wedges
  • More complex wedges such as split wedge
  • Variable toe in/out across column wear surface

IMPROVED SUPPORT PROGRAMS

  • New SYS File preprocessor to replace PREVU
  • Updated TRAKVU features
    • More batch capability
    • Improved TRK file creation including capability for longer TRK files

IMPROVEMENTS TO NUCARS®

  • Parameter variation capability
  • Improvements to along-track profile variations in W/R penetration model
    • Includes multiple wheel profiles
