“Romax Designer 24”

Romax Designer 24 is a powerful, industry-leading software solution developed by Romax Technology (a Hexagon company) for the design, simulation, and analysis of drivetrain systems. Widely used in automotive, aerospace, wind energy, and industrial machinery sectors, Romax Designer 24 enables engineers to model, validate, and optimize complete transmission systems with high precision and efficiency.

Key features of Romax Designer 24 include:

1. Integrated System Modeling: The software provides a comprehensive 1D/3D modeling environment where users can build detailed virtual prototypes of entire drivetrains, including gears, shafts, bearings, housings, and couplings, within a single platform.

2. Advanced Simulation Capabilities: Romax Designer 24 supports multi-physics simulations, including structural, thermal, and dynamic analyses. It enables accurate prediction of load distribution, efficiency, vibration, noise (NVH), and durability under real-world operating conditions.

3. Gear and Bearing Analysis: The software includes sophisticated algorithms for gear contact analysis (GCA) and bearing rating calculations, allowing users to evaluate stress, deformation, fatigue life, and microgeometry effects such as crowning and lead correction.

4. NVH (Noise, Vibration, and Harshness) Prediction: With built-in tools for modal analysis, transmission error calculation, and system-level vibration simulation, Romax Designer 24 helps engineers identify and mitigate noise and vibration issues early in the design process.

5. Design Optimization and Automation: Users can perform parametric studies and automated design exploration using integrated optimization tools. This supports rapid iteration and helps achieve optimal performance, weight, and cost targets.

6. Durability and Life Prediction: The software calculates component and system-level fatigue life for gears and bearings under complex loading conditions, supporting reliability-driven design.

7. Interoperability and CAD Integration: Romax Designer 24 seamlessly integrates with major CAD platforms (such as Siemens NX, CATIA, and SolidWorks) and CAE tools, enabling smooth data exchange and collaborative workflows.

8. Reporting and Collaboration: Customizable reporting tools allow users to generate detailed technical reports, including simulation results, design validation data, and compliance documentation, facilitating communication across engineering teams.

Typical applications of Romax Designer 24 include:

• Design and refinement of automotive transmissions (manual, automatic, EV gearboxes)
• Wind turbine gearbox development and reliability assessment
• Aerospace drivetrain systems
• Industrial gearboxes and power transmission units

With its enhanced user interface, improved solver performance, and expanded material and manufacturing databases in the 2024 release, Romax Designer 24 delivers greater accuracy, faster computation, and deeper insight into system behavior. It empowers engineering teams to reduce physical prototyping, accelerate time-to-market, and improve product performance and reliability.

Romax Designer 24 is an essential tool for modern drivetrain engineering, combining deep technical capabilities with practical usability for innovation across a wide range of mechanical systems.

Romax Spectrum

Advanced JMAG-Designer Interface for eNVH Optimisation

The drive towards zero prototypes calls for CAE solutions that not only give accurate predictions, but which also support variability analysis and rapid what-if studies. In the field of electric powertrains, it is noise and vibration that has proved to benefit particularly from a simulation-led design approach.

To allow easy optimisation of electric powertrain noise and vibration, the ability to perform automated studies of the combined effects of both motor and gearbox design changes is needed. Therefore, this release of Romax Spectrum introduces a new feature, the “JMAG Force Automator,” which allows the modification of electric machine parameters and the generation of excitations from a JMAG Designer analysis to be controlled from within Romax DT. This enhancement allows workflow automation, parametric studies and optimisations to be performed with ease.

This development also eliminates the need to export and import files manually, making the process more efficient and less error prone.

• Model parameters can be tweaked to easily compare NVH performance
• Excitations can be generated within the parametric study and batch running
• New actions and targets were added to parametric study and batch running to see the effect on excitations
• Metadata is added when importing excitation data from any source
