Smarter Decisions Faster: Announcing Romax R20
Last year, we were very proud to introduce our reimagined ecosystem of applications, Romax Concept, Enduro, Spectrum, Energy, Spin and Evolve, united within the Romax platform. Now, a year on, we bring you the next chapter in our journey, with the announcement of Romax R20.
At Romax, we always strive to continuously improve in everything that we do. We understand the constantly-evolving drivetrain industry, and are driven to ensuring we provide our customers with software that can keep them ahead of the innovation curve. A result of working closely with our customers and partners, as well as our own technological innovations, our new features are designed to help you stay at the cutting edge of technology.
New features are available across all of our product portfolio, with some enhancements available in multiple products.
In Romax Concept, we have focused on broadening the usage of the vehicle simulation tool, for ease of use and to allow comparison of a wider variety of designs. We have also developed an enhanced bearing stiffness model, which offers more accurate results which will be more consistent between Romax products. Further improvements to usability, reporting and gear design ensure that Concept remains the fastest, most user-friendly tool on the market for early stage transmission and driveline design and analysis.
In Romax Enduro, we have made improvements to our cutting-edge gear root stress analysis capability, in particular to include virtual strain gauge calculation in the normal as well as in the transverse plane, for easier comparison with experiment. Additionally, we have added new variables, actions and results, mostly related to gears and gear root stress analysis, to parametric study and batch running. This ensures that Romax Enduro continues to provide industry-leading structural and durability analysis of electromechanical drive systems, strengthened by automatable optimisation processes.
Romax Energy sees the inclusion of three new ways to model energy loss: ISO/TR 22849:2011(E) to predict bevel and hypoid gear efficiency based on tooth profile, sliding and churning; Changenet oil churning models (2007 and 2011) to predict accurate churning losses; and a new industry-leading proprietary bearing drag model which accounts for all bearing geometry, operating conditions due to misalignment and load, and detailed lubricant traction properties. Together, they provide our customers with more options for predicting electro-mechanical transmission efficiency.
Romax Spin, our specialist tool for advanced bearing simulation, has now extended its unique, fast, validated capability for subsurface stress analysis to include roller bearings. This will be of interest to bearing suppliers and OEMs who are looking to determine a suitable case hardening treatment that balances cost and reliability.
Romax Spectrum provides full system NVH simulation from gear and electric machine design through to vibration and radiated noise. In R20, new features for Acoustic Analysis (also available for Romax Evolve) include the capability to view and update shrinkwrap meshes for quality assurance as well as an improved user experience and tighter integration with FFT Actran for superior simulation efficiency. To further support process automation and optimisation, Spectrum R20 now supports the calculation and export of Mean Square Normal Surface Velocity using batch processing and parametric study.
Romax Evolve, our dedicated tool for electrical machine structural design and analysis, includes interfaces to several electromagnetic software tools. Whilst links to Motor-CAD and Dassault Opera have existed since 2017, R20 adds JMAG and Ansys Maxwell to help a broader variety of users streamline their workflows. Additionally, the new release allows electrical machine excitations to be estimated, which enables fast initial indication of response amplitude when excitation data is not available for import. Both of these new capabilities are also available in Romax Spectrum, for analysis of the electrical machine as part of a whole system.
Applicable across the products are updates including a new bearing database from Nachi-Fujikoshi, a new modelling process to speed up the building of complex shaft arrangements, with automatic detection of connection locations, the ability to import reference geometry directly from CAD for effective visualisation and communication, significant improvements to speed and performance, and additional results and variables available in parametric study and batch running. These improvements are all designed to enhance the user experience and ensure that our platform of products continue to meet the demands of our evolving industry.
