Romax R18 Software Suite

Electrification, Technology, Integration

Romax Technology’s world-leading R18 Software Suite gives you faster and more powerful design, simulation and analysis capabilities for electrified and conventional drivelines within a streamlined and integrated environment.

Electrification – for seamless integration and collaboration

  • Import geometry and excitation data directly from MDL’s Motor-CAD and Cobham’s Opera

In partnership with Motor Design Limited and Cobham, RomaxDESIGNER R18 further advances capabilities in electrification with interfaces to Motor-CAD and Opera software tools. This collaboration speeds up and facilitates model creation and reduces the time required to prepare the model for NVH analysis, enabling users to simulate a wider range of electric machines within a model. This integrated NVH analysis of the complete electric machine and gearbox system gives you the engineering insight you need to deliver quality products faster and at lower cost.

Gear technology – for design, analysis and optimisation

 

  • Interface with the Gleason GEMS platform
  • Advanced root stress analysis
  • Improved gear design workflow including tolerances and asymmetric gears
  • Combined shear stress plot for gear contact

In partnership with Gleason, R18 offers data exchange between RomaxDESIGNER and the Gleason GEMS platform, enabling more system-based calculations to inform effective gear design and optimisation for bevel and hypoid gears.

R18 extends Romax’s advanced root stress capability, with batch running, multi-mesh analysis and inclusion of thermal and centrifugal effects enabling in-depth durability analysis for high performance, high speed, lightweight gears.

Further capabilities for the design of high performance gears include asymmetric gear tooth design for strength and efficiency, improved tolerancing analysis for design robustness and combined shear stress analysis for optimising surface finish.

Bearing technology – for reliable simulation and design data management

  • Updated bearing catalogs, with ability to download updates as they are published
  • Improved bearing modelling

Romax Technology’s strong partnerships with key bearing suppliers is manifested in RomaxDESIGNER R18’s updated bearing catalogs from major suppliers SKF, Timken and Schaeffler (INA and FAG), with a cloud-based download system so that your catalogs are always accurate and up to date.

Improved bearing mounting options and easier modelling of complex bearing axial connections provide an efficient and error-proofed process which gives reliable analysis results quickly.

Automation and productivity – for accelerating simulation efficiency

 

  • Isight, modeFRONTIER, Optimus integration
  • Condensation times reduced by more than 10 times for FE components with many modes
  • Dynamic analysis, calculation of vibration response and operating deflection shape for FE-heavy NVH models up to 20 times faster
  • Saving of NVH results
  • Improvements to custom reporting, parametric study and batch running

Increased integration with automation and optimisation tools Isight, modeFRONTIER and Optimus provide further time savings and increase the potential for simulation to explore new and optimised designs.

Major improvements to the performance of NVH analysis for large complex models provides an order of magnitude speed-up for FE condensation and dynamic analysis giving you enhanced productivity, especially for FE-heavy models and optimisation and sensitivity studies. Combining this with the ability to save NVH results independently from the design file means you can spend less time simulating and more time getting the engineering answers you need.

Enhancements in custom reporting, parametric study and batch running offer more functionality to Enterprise users.
