FVA 764 I Tooth Mesh Modeling for System Simulation


Efficient dynamic simulation of tooth meshing for use in drive systems with a highly variable operating range



For cost-effective and less computationally intensive modeling, a model should be constructed with a homogeneous level of detail. The currently available methods cannot fully meet these requirements with regard to the simulation of drive systems with gear stages. Some approaches offer a rather rough approximation of gear characteristics, while others target the reproduction of very detailed properties in the tooth contact, rendering the simulation of large systems nearly impossible.


Research objectives

The objective of "Tooth Mesh Modeling for System Simulation" is to provide an adequate and homogeneous level of detail within multi-body simulation for current and future system simulations of drive trains with gear stages, both spur and planetary.

  • Bridging the definition-gap between the roughly approximated and the extremely detailed modeling approaches of tooth meshes
  • Preserving the dynamic behavior of elastic gear bodies
  • Modeling of tooth mesh excitations over wide operating ranges through the use of pre-calculated stiffness characteristic arrays
  • Positionally accurate force application and load distribution relative to the gear body
