 Press Releases

  • Romax are pleased to announce the 2021 release of the complete Romax software suite: Concept, Enduro, Spectrum, Energy, Spin and Evolve. The 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.

    Virtual Gear Manufacturing with Dontyne

    Closing the loop on gear simulation and manufacturing

    Even though their roles greatly impact each other, existing gear design processes often mean disconnects between the gear manufacturer and the gear designer. The gear designer might decide on a design that performs well in simulation but cannot be manufactured to the required specification. This may mean the gear design is changed during production, which can lead to long delays and high cost, as well as differences in the expected performance for NVH, durability and efficiency.

    With this new technology, we have embedded Dontyne’s gear manufacturing simulation capability into Romax Enduro’s gear design and analysis tools meaning that gear design, analysis and manufacturing can be considered virtually for the first time. This leads to reduced development costs, shorter time to market, and greater confidence in the manufactured product.

    Lubrication simulation with Particleworks

    Democratising CFD analysis

    Lubricant distribution predictions and churning loss simulations are typically not an early part of a transmission design process. This is because CFD analysis requires significant modelling and simulation time along with high levels of expertise, so is typically done when the design is finalised, or when a prototype has been manufactured.  This means that problems are typically found late in the design and development process, when it is much more expensive to resolve issues.

    In the 2021 release, we have developed a new interface between Romax Energy and Particleworks, to enable CFD analysis to be performed as soon as you have a Romax Energy model, early in the design process.  This is true “CAE-led design”, enabling transmission engineers and non-CFD specialists to conduct informative CFD simulations to gain insight into lubricant distribution within the transmission and understand the effect on churning losses, allowing them to optimise for efficiency, improve product quality and reduce time to market.

    In-vehicle NVH simulation with VI-grade

    Virtually test drive your powertrain designs in real-time for in-vehicle sound quality assessment

    Engineers are always seeking to improve product quality, with NVH, in particular, being a key differentiator in a crowded market. To do this, engineers need to understand how the powertrain noise will sound in the vehicle cabin before it is manufactured. Additionally, there are challenging drives to reduce prototyping and testing cycles, again demanding better understanding of product performance. In 2021, we have expanded our interface with VI-grade’s technology, to allow our users to apply a CAE-led design approach to the world of vehicle NVH testing. Romax Spectrum’s accurate prediction of gearbox and electric powertrain noise and vibration can now be automatically calculated and exported for use in the VI-grade NVH simulator, which uses a mix of test and simulation data to provide a virtual driving experience that accurately represents in-vehicle noise from all sources. By presenting complex CAE simulation results in a way that anyone can interpret and understand, this feature will democratize advanced technologies and aid with cross-departmental collaboration.

    Interface with JMAG-Express

    Integrating mechanical and electromagnetic solutions

    Romax has been rapidly building on capabilities for electromechanical solutions for the last 15 years. Whilst processes are much improved, engineers still need better ways to understand the mechanical performance of electric motor early in the development process, with access to multi-fidelity simulation tools. Romax Evolve provides such a multi-fidelity environment for mechanical simulation of electric machine durability, NVH and efficiency, whilst Romax Concept is a fast simulation tool for early stage development of the complete electric drivetrain. Both tools have now gained an interface to JMAG Express, a concept-level online parametric design tool for motor electromagnetic performance. Linking these tools together provides a fast, easy workflow at the concept and sizing development stage when design iterations need to be at their most efficient. This provides an enhanced workflow integration for motor designers looking to understand motor and electric powertrain efficiency performance right from the start.

    Further enhancements include:

    • Inclusion of motor efficiency maps, to calculate overall energy loss for an electrified driveline
    • Show velocity on housing in Acoustic Analysis– to see the local structural deformations at the same time as the acoustic results and use this to interpret the source of any directional noise
    • Vehicle performance and efficiency predictions on electric powertrain designs using vehicle, transmission and electric machine data in Romax Concept
    • FE speed improvements for a significant decrease in model preparation and solve times
    • SKF bearing calculations from SKF’s cloud calculation service embedded into Romax software
    • Hybrid bearings, with steel rings and ceramic rolling elements
    • Import REXS files, a standardised file format for exchange of geared system CAE models
    • Electric machine NVH workflow enhancements, including for skew and eccentric rotors
    • Improvements to batch running and parametric study to enable more optimisation and sensitivity studies

  • A new technology collaboration between Romax software and Dontyne Systems will help the industry bring the worlds of gear design and manufacturing closer together, leveraging high-end manufacturing simulation from Dontyne and Romax’s trusted, fast, system design and analysis tools.

    It is widely acknowledged that there is a disconnect between design engineers and the production department or supplier, which in some cases can significantly increase the development times and costs. Such is the case with gears, which are highly sensitive to even micron-level deviations in their system performance. The tooth geometry determined by the design engineer often cannot be produced precisely as specified. Even small adjustments made by the manufacturer due to the limitations or intricacies of the manufacturing method can invalidate the design intent. This is exacerbated by manufacturing variability, which adds further uncertainty.

    The impact of gear manufacturability can be severe. If unwanted deviations are found during production, the options to fix this are limited. If the tooling has already been purchased, retooling is expensive and would mean wasted costs on the original tooling. Alternatively, manufacturers can correct for unwanted errors during production, but this can take considerable time, slowing down the production with long cycle times, and requiring additional manufacturing processes and specialist tools and machines that can incur significant extra costs. In certain cases, a late-stage redesign may be required which can lead to long project delays. It is far less expensive and far quicker to resolve these issues during the design stage as opposed to the manufacturing or production stages.

    However, the design engineer is rarely equipped with the right tools and expertise to take into consideration such issues at the design stage.

    Together with Dontyne, we are collaborating to address this and create solutions that enable the design engineer to consider the manufacturing process at the design stage, without requiring deep gear manufacturing expertise. The first results from this collaboration have recently been released with the 2021 version of Romax software in the products Romax EnduroRomax Spectrum, and Romax Energy. The new features will allow more accurate gear geometry to be considered for tooth contact analysis for system durability, NVH, and efficiency respectively. In this first release, we support pre-finish hobbing combined with worm (generation/continuous) grinding or form (profile) grinding simulated using Dontyne’s technology. Other processes and features are in development for future versions.

    The manufacturing simulation provided by Dontyne’s powerful software is seamlessly integrated into the Romax products. We have been able to make it fully automatable and able to take as inputs the existing gear parameters that Romax users are familiar with. The tooling parameters are automatically estimated based on the designed geometry. This means it is not necessary to have a deep understanding of gear manufacturing to use it. However, it is also possible to view all the details of the tooling and the gear finishing simulation performed by Dontyne, and have more manual control for those expert users who require it.

    Romax Dontyne

    Unlike other solutions, being fully integrated into Romax and automatable, the accurate gear geometry is always considered in the context of the full drive system for durability, NVH, and efficiency analysis; it is very easy to use, and it can be run as part of parametric studies or in batch mode.

    It is also possible to export gear sets from Romax and open these in the full version of Dontyne’s Machine Centre, which will enable Romax users to directly provide data to gear manufacturers who use Machine Centre for the detailed tooling design and other manufacturing aspects.

    Dr Michael Fish, Co-founder, Dontyne Systems comments “Dontyne was formed to improve communication along the gear production process to enable greater production efficiency and product performance. Our software allows better integration of design and manufacture data to quickly assess the influence of each on the other so that problems can be identified and adjustments made, if required, before commitment to machining. During the development of our software we have always kept in mind that it must be flexible enough to integrate with existing systems for maximum utilisation and lowest cost to customers. Our collaboration with Romax is perfectly suited to this end and will benefit both companies and the industry in general. We are looking forward to expanding the scope of the collaboration in future releases.”

    Kristian Kouumdjieff, Product Manager Romax Enduro, Hexagon, comments: “We are excited about the possibilities this partnership opens and the technologies we can develop and bring into practice together. We are looking forward to working with Dontyne and with our customers and partners to improve industry practices for the development and production of geared electro-mechanical drive systems.”
