Calam is a semi-analytical calculation code designed to predict the quasi-static behavior of splines. Calam is co-developed with Safran and the LaMCoS laboratory of INSA Lyon.
Calam
Capabilities
- Straight involute splines
- Flat or circular tooth root
- Micro-geometry (Hob trajectory modification)
- Manufacturing errors (pitch, helix, profile errors)
- Misalignments
- No teeth coupling
- Contact planes specific to each tooth
- Meshing over the entire tooth flank
- Structural flexibility (shafts) taken into account by preliminary FE calculations
- Tooth bending : mixed FE/analytical influence coefficients method
- Contact deformations: simplified Boussinesq and Cerruti analytical formulations (normal contact effects only)
- Mirror method to avoid numerical edge effects
- Maximum pressure envelope
- Instantaneous pressures
- Load distribution between the teeth
- Stiffness
- Tooth root stress fields
- Loads export for structural stresses
