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.

Features

• 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 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

Easy Track Generation Using RecurDyn/TrackHM

Benefits

• 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
  • Shoe pad shape design

• Optimize suspension spring rates, damping and controller (whether passive, semi-active, or active)
• Optimize track tensioner to stabilize tension
• Assess performance of turret and weapon controllers during maneuvers
