Spiralam is a semi-analytical calculation code designed to predict the quasi-static behavior of spiral bevel gears. Spiralam is co-developed with Safran and the LaMCoS laboratory of INSA Lyon.
Spiralam
Capabilities
- Import of Gleason or Klingelnberg geometries (meshes or point mapping)
- Micro-geometry (crowning, pressure and spiral angle differences, etc.)
- Manufacturing errors (import of measurement files)
- Misalignments
- Teeth coupling
- Parallel contact planes on all teeth
- Mesh slipped around potential contact lines (outside the action plane)
- Structural flexibility (shafts, webs) taken into account through preliminary FE calculations
- Tooth bending : mixed FE/analytical influence coefficients method (normal contact effects only)
- Contact deformations: simplified Boussinesq and Cerruti analytical formulations (normal contact effects only)
- Mirror method to avoid numerical edge effects
- Non-loaded contact paths
- Non-loaded contact fields
- Non-loaded kinematic error
- Operating gaps
- Tooth root gaps
- Slip speeds
- Loaded transmission error
- Pressure fields
- PV and PVT Almen factors
- Load distribution between teeth
- Stiffness
- Tooth root stress fields
- Haigh diagrams
- No-load modal analysis
- Loads export for structural stresses
- Calculation of bearing forces (analytical modeling)
