R21新功能

The 2021 Romax release sees new features across the simulation portfolio, with a particular focus on enabling our customers to democratize advanced technologies and to work in more collaborative ways. The key new features in Romax Spin are:

SKF bearing calculations from SKF’s cloud calculation service embedded into Romax software. The SKF bearing catalogue has been updated and now includes super precision and hybrid bearings.
Hybrid bearings, with steel rings and ceramic rolling elements, are supported including the capability for calculations of load capacity, life, stress, and efficiency. Fully ceramic bearings are also supported but the standards do not support calculations of load capacities and life.
New specialised bearing type: asymmetric taper roller bearing
New results available: bearing ring hoop and radial stresses due to press fits
Application of micro-geometry profile modifications to inner/outer surface of hydrodynamic journal bearings
Support for asymmetric spherical roller bearings in Customized reporting
Bearing ring temperatures available in the Temperature Spreadsheet

Feature Highlight: Romax Bearing Dynamics

With the rise of electric vehicles, bearings are operating under increasingly high speeds. Combined with low load conditions, this can lead to a dynamic phenomenon known as bearing skidding. In certain circumstances, bearing skidding can generate excessive frictional heat and high surface shear stress, and subsequently result in efficiency issues or premature bearing failure.

Romax’s Bearing Dynamics application uses a novel approach based on transient time-domain analysis to predict the occurrence of skidding in electric-vehicle bearings in a matter of minutes. The model considers structural, thermal and fluid domains, including the influence of centrifugal and gyroscopic effects on rolling- element dynamics, heat generated by the lubricant and associated temperature rise, and rheology and traction behaviour of the lubricating oil.

This application helps design engineers and bearing analysts to avoid damaging failures by designing more reliable bearings and selecting better lubricants, through unique insight of the underlying skidding mechanism and bearing dynamics.
