Durability Analysis
MASTA’s comprehensive system analysis ensures durability calculations accurately reflect real-world conditions.
Durability is essential in the design of transmissions, electric machines and electrified powertrains. MASTA delivers high-accuracy durability analysis by considering the components with the context of the full system, taking into account deflections under load, thermal expansion, manufacturing and assembly deviations and power losses.
ISO and AGMA Gear Ratings at the click of a button
- Ratings for failure modes such as pitting, root bending, micro pitting, scuffing and tooth flank fracture
- Advanced assessments, considering gear micro geometry design, and assess high contact ratio and asymmetric gears via high fidelity loaded tooth contact analysis
- High fidelity tooth interior fatigue fracture analysis
- Consider manufacturability during the design process
- Cutter tip optimisation for maximum bending durability
- Automated optimisation of gear micro geometry via AI based optimisation
- Detailed consideration of load sharing and the effects of assembly and manufacturing errors in planetary and other multi torque path systems
FE Accuracy, MASTA Speed
- MASTA’s Advanced Loaded Tooth Contact Analysis makes Micro Geometry optimisation orders of magnitude faster than traditional FEA workflows. SMT’s innovative Hybrid Hertzian-FE contact model means that accurate contact analysis in MASTA takes seconds rather than hours in FEA.
- As part of Advanced LTCA, MASTA is able to calculate tooth root stress with high fidelity.
- Advanced LTCA results can be used to further increase the fidelity of gear ratings.
Advanced Bearing Analysis
- Bespoke non-linear contact models
- Consider the effects of internal geometry, clearances, thermal expansion and fitting effects
- Ratings for static and fatigue failure
- Bearing catalogues for all major types and many suppliers
