Drivetrain

RecurDyn/DriveTrain is a solution that enables to model and simulate the components of a drivetrain consisting of gears, bearings, shaft, and other components. 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 calculate a variety of results including Transmission Error for noise and vibration evaluation by using RecurDyn's dynamic solver, KISSsoft's Gear Analytic Contact and tens of thousands of bearing libraries.

GearKSRecurDyn/GearKS provides an intuitive Gear Modeler and built-in KISSsoft UI for gears. It supports Spur, Helical, and Planetary Gear, enabling analyses with detailed gear geometries. It predicts accurate Transmission Errors through theory-based contact specialized for gears. 


1. Gear Analytic Contact specialized for gear analysis (SMP is supported)

2. Provides various gear analysis results including Transmission Error (TE)

3. Intuitive gear modeler

4. Supports Spur Gear, Helical Gear, and Planetary Gear

5. Supports gear geometry and detailed tooth modeling

6. Provides various Tooth Tolerance libraries and Material libraries

7. Automatic calculation of gear backlash based on inputs

8. Detailed modeling and analysis/post-processing through built-in KISSsoft UI specialized for gear

  • Precise gear design with parameters used for actual gear design
  • Interoperability of the gear models between KISSsoft and RecurDyn (Z12 Import, Export)
  • Supports gear static analysis
  • Various results such as stress distribution on the gear tooth surface

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.

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