What's New: MD Adams R3

Product Integration

  • Common MD Database (MD DB) format for flexible body which allows for storage of several flexible bodies in a single MD Nastran file (.MASTER).
  • Element-level Adams2Nastran export allows for individual components of the entire system to be more easily replaced when using the white box export option.
  • Adams/Mechatronics (new plugin) for Adams/View standardizes how control systems are integrated with multi-body system models.

Performance

  • Faster animation speed for flexible bodies and modal force contouring helps you visualize your results sooner.
  • 64-bit support on Windows and Linux platforms combined with improved processing speed when importing XML results files help to make large scale models easier to deal with.
  • Parallel processing support for Adams/Tire results in faster run times on multi-CPU machine when using SMP with Adams/Solver (C++).

New Capabilities

  • 3D Contact is now enhanced to support contact between modal flexible bodies and solid geometry when using Adams/Solver (C++).
  • Adams/Car capabilities have been extended and usability improved with General Actuation Analysis (GAA), a new Road Builder for analytical roads, as well as a consolidation of suspension test rigs.
  • Adams/SmartDriver has been enhanced with a utility for path planning which support corner cutting, a new discrete GSE implementation for improved accuracy at larger output steps, and capability for driving backwards.
  • Quantitative Ride Index measures in Adams/Car Ride are handy for quantifying ride quality and assessing vibration impact on occupants.
  • Hiller-Anantharaman STIFF integrator (HASTIFF) with SI1 and SI2 formulations requires fewer function evaluations to converge and has improved stability at small time steps.
  • New DELAY run-time function is available in Adams/Solver (C++) can be used to introduce signal and actuator delays in controller models.

Other Additions

  • Adams/Tire 3D tire modeling technology is suitable for use on uneven road surfaces.
  • A new command line utility, MNFXFORM, is useful for mirroring a flexible body MNF, or transforming/rotating the flexible body coordinate system.
  • New documentation added for plugins and usability enhancements.
