RecurDyn/HM-Track (High Mobility Track Toolkit) gives the ability to simulate military-style, high mobility tracked vehicles, where the track shoes are typically defined as a combination of a steel frame and track pads. Band track with similar characteristics can also be modeled. The toolkit supports the definitions of sprockets, roadwheels, idlers and the initial track shoe which is replicated along a user-defined path.


  • Calculate dynamic load history for stress and fatigue analysis
  • Study dynamic performance of vehicle
    • Determine energy transferred to crew
    • Observe vibration due to discrete track links
    • See separation of track link from sprocket and idler
    • Use library with various terrains (bump, trench, ditch, cross country)
  • Component Optimization
    • Sprocket teeth profile design
    • Grouser shape design
  • Optimize suspension spring rates, damping and controller (whether passive, semi-active, or active)
  • Optimize track tensioner to stabilize tension
  • Assess performance of turret and weapon controllers during maneuvers


  • Library of custom geometric entities
  • Automated track assembly
  • Graphical user interface for fast and easy model generation
  • Graphical design of sprocket teeth profile (lines and arcs) and link grouser profile (line segments)
  • Efficient contact algorithms yield fast, robust simulations
  • Easy creation of terrains, with a library of standard proving grounds
  • Subsystem capability allows each track assembly to be created and simulated separately, then integrated into the vehicle model
  • Integrated Bekker Soil Model with additional soil definition options using parameters and/or a user-defined function
  • Plotting of specific results such as track link contact forces and track tension
