RecurDyn TrackLM (Track Low Mobility) is a toolkit which provides the modeling function of moved vehicles by the track in the construction equipment or the heavy industry equipment and the simulation function. Main elements of tracked vehicle are provided as libraries and the user can perform the fast analysis by the optimized solver.

RecurDyn TrackLM supports the following functions

  • Link
  • Roller Guard
  • Standard proving ground library
  • Soil modeling by the Bekker’s theory
  • Sprocket with freely editable profilestracklm.jpg
  • Optimized solver for the high speed simulation
  • Single Flange, Double Flange, Center Flange, Flat Roller
  • Link Flange, Roller, Roller Guard, Sprocket 3D Contact


  • Study dynamic performance of vehicle
    • Ride and comfort
    • Vibration due to discrete track links
    • Link separation from sprocket and idler
    • Traversal of multiple terrains
  • Calculate dynamic load history for stress and fatigue analysis
  • Component Optimization
    • Sprocket teeth profile design
    • Grouser shape design
  • Optimize suspension spring rates and damping
  • Optimize tensioner to stabilize track tension


  • Graphical user interface for easy and fast model generation
  • Library of custom 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 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
  • Open loop track assembly
