SABR - bearing analysis
SABR is able to model deep-groove and angular-contact ball bearings, and tapered, cylindrical and needle roller bearings that are casing mounted or encapsulated within two rotating components. The bearing life, misalignment and loading algorithms form the backbone of SABR and are based on bearing calculations that bearing design and manufacturing companies use, including the ISO 281 and ISO 16281 standards. A close relationship with bearing companies has advanced the evolution of SABR with Koyo, SKF and Timken bearing catalogues included as part of the suite. SABR can calculate and visually represent the exact loading regime of the bearing, showing the stress distribution and utilisation of the bearing race as well as potential areas of excessive load.
- Analysis of standard and custom bearings
- Life calculation, taking into account bearing misalignment, roller crowning along with loading, preload and clearance
- Editable roller and raceway profiles allow all bearing designs and their application to be considered
- Visual display of loading regime on the bearing raceways
- Preload assessment to understand how stiffness, stress, durability and frictional loss are impacted by applying preload
- Efficiency calculations combining load and speed dependent losses according to ISO 15312
- Bearing positioning tool allows fast iterative assessments of transmission layout
- Integrated bearing catalogue and ability to define bespoke bearing catalogue
- Casing stiffness matrices can be imported from major FE packages, or reduced using the Realis FEARCE solver
- Bearing loads can be exported for visualisation on finite element (FE) meshes of the outer races, and as input for casing FE contact analysis to aid casing design decisions
