TrackHM 글 편집

RecurDyn/TrackHM (Track High Mobility) gives the ability to simulate military-style tracked vehicles such as tanks, armored 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 track links, sprockets, roadwheels, idlers and the initial track shoe which is replicated along a user-defined path.

TrackHM is a fast, accurate, and user-friendly track simulation toolkit, often used for the simulation of military vehicles, including:

• The simulation of tank behavior
• The simulation of armored vehicle
  

Tank simulation using TrackHM

Features

• Graphical user interface for easy and fast modeling and simulation of track assembly for military vehicles
• Fast and accurate simulation solver specialized for track assembly
• Various libraties of custom 3D geometric entities for high mobility tracked vehicle.

• Graphical design of sprocket teeth profile (lines and arcs) and track link shoe pad profile
• 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 
• Plotting of specific results such as track link contact forces and track tension
