TrackLM 글 편집

RecurDyn/TrackLM (Track Low Mobility) gives the ability to simulate construction-style tracked vehicles. The toolkit supports the easy creation of sprockets, rollers, idlers and link. Also, graphical design of sprocket teeth profile and grouser of the track link is supported.

RecurDyn TrackLM-Main


  • Graphical user interface for easy and fast model generation
  • Fast and accurate solver specialized for Track model
  • Library of custom 3D geometric entities:


  • Graphical design of sprocket teeth profile (lines and arcs) and link grouser profile (line segments)
  • Automated track assembly
  • 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's 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

Easy Track Generation Using RecurDyn/TrackLM



  • Calculate dynamic load history for stress and fatigue analysis
  • Study dynamic performance of vehicle
    • Evaluation of the ride quality, the crew comfort, and the safety
    • 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
