EDware SAR


Squeak And Rattle analysis software

(squeaks, creaks, and rattles) for Nastran and Abaqus models

  • EDware SAR is a unique knowledge based analytical software, which is used to find the locations on all complex mechanical or structural assemblies that tend to creak and rattle.
  • EDware SAR offers a simple, economical, real-time based solution to eliminating noise issues during a very early stage of product development.
  • EDware SAR identifies potential rattle and creak points for Nastran and Abaqus models fully automatically.
  • EDware SAR V6, the latest higher performance, easier to handle version is now available.
