RecurDyn Toolkits

RecurDyn/DriveTrain

RecurDyn/DriveTrain is a solution that enables users to model and simulate the components of a drivetrain consisting of gears, bearings, shaft, and other components (especially for gear train simulation and bearing simulation). It consists of 3 toolkits: GearKS, BearingKS, and Shaft. Users can easily simulate and analyze drivetrain systems with specialized modelers that can easily create gears, bearings, and shafts, a specialized solver, and dedicated post-processing. In particular, GearKS and BearingKS have been developed through the technical partnership with Gleason’s KISSsoft . This allows users to accurately capture not only transmission error for noise and vibration evaluation but also other results by using the RecurDyn’s dynamic solver and KISSsoft’s Gear Analytic Contact.

Advantages of Gear Analytic Contact of RecurDyn/DriveTrain

Since Transmission Error is a very small value (µm), accurate contact calculation is crucial. FunctionBay provides accurate Gear Analytic Contact through technical cooperation with Gleason/KISSsoft for advanced gear simulation.

  • Theory-based contact calculation considers detailed gear design parameters
  • Considers deformation of gear teeth
  • Considers tolerance of gear teeth
  • Contact available in dynamic gear simulation
