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.

Romax Enduro
Cylindrical Gears – ISO1328-1:2013 Gear Accuracy Specification
Gear accuracy is a measure of manufactured gear quality and affects durability, noise & efficiency. Higher quality gears will give improved performance, but cost more to produce, have longer manufacturing times and potentially higher scrap rates
This development adds the ability to specify cylindrical gear accuracy according to ISO 1328-1:2013 to complement the older implementation of ISO 1328-1:1995. This is an important enhancement as the latest ISO 6336:2019 rating used by Romax Enduro to assess gear durability is not compatible with the older version of ISO 1328.
Ability to specify different quality parameters/grades for each gear
Specification of individual grades or individual deviations
Ability to approximately compare different quality standards
Addition of quality specifications as variables in Parametric Study and Batch Running
Estimation of grades when specifying deviations and helpful messages guiding the user
Note that because all the quality standards work slightly differently, setting individual parameters and comparing between standards is an approximation. In a lot of cases, this can cause non-compliance with the standard. However, Romax users have to deal with these situations frequently, so this development is designed to be flexible and transparent to the user. Colour coding and helpful messages make it clearer to the user. It is the responsibility of the user to check if the results are suitable for their specific requirements.

Romax Energy

Cylindrical Gears – Changenet Gear Loss Model Enhancement

In previous releases of the Changenet gear loss model the gear meshes were required to share a singular lubricant sump (defined at the gearbox level), from which all lubricant properties were derived.
This enhancement allows for individual gears to have a separate lubricant applied, with the differing properties that affords.

ISO Tolerances for gear and bearing press fits

Press fits have been used in Romax for many years to enable the calculation of bearing radial internal clearances, hoop stresses, shaft fatigue and also the new DIN 7190 interference fit calculations. In this release, press fits can now be defined from ISO standard tolerance classes by selecting from drop-downs. The deviation values will be populated automatically according to the relevant standard.

• ISO 286-1:2010 for gears, shafts and housings
• ISO 492:2023 for bearings

This enhancement allows the user to easily choose standard tolerance combinations instead of manually specifying deviation values. This will save users time and reduce errors by removing the need to look up the appropriate deviations in the standards.
