TrackHM 글 편집

RecurDyn/TrackHM (Track High Mobility) gives the ability to simulate military-style 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.

  • Graphical design of sprocket teeth profile (lines and arcs) and shoe pad profile
  • 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
