TrackLM 글 편집

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

TrackLM is a fast, accurate, and user-friendly track simulation toolkit, often used for the simulation of construction machinery, including:

  • The simulation of track behavior
  • The simulation of excavator operations
  • The simulation of dozer

features of track toolkit - sprocket - flange - track link

  • Graphical design of sprocket teeth profile (lines and arcs) and track link grouser profile (line segments)
  • Automated track assembly modeling
  • Efficient contact algorithms yield fast, robust simulations
  • Easy creation of terrains, with a library of standard proving grounds
  • The subsystem capability allows for the separate creation and simulation of each track assembly, followed by their integration into a single tracked vehicle model for comprehensive simulation.
  • Soil modeling with Bekkers theory
  • Track link can be converted into flexible body for MFBD simulation
  • Plotting of specific results such as track link contact forces and track tension
