Romax Designer v14.5
Romax Designer v14.5

The package for calculation and transmissions for ground transportation and industrial facilities

RomaxDESIGNER is the product of choice for ground vehicle transmissions - from motorcycles to off-highway equipment - and is licensed by 14 of the world's top 15 automakers.

It is also used widely in the design of stationary products and industrial equipment including the world's largest wind turbine systems and is acknowledged as the industry standard for this rapidly expanding global market sector.

RomaxDESIGNER is a virtual product development and simulation environment for the design, analysis & NVH exploration of the complete transmission - gearboxes, bearings, drivetrains and all components.

Reduce the development-analysis chain

RomaxDESIGNER can significantly reduce the number and length of design cycles by considering all system effects in just one transmission model. From the initial concept stages, component lives are calculated providing a fast and efficient method for system development.

RomaxDESIGNER can eliminate the need to switch between numerous software packages to calculate the different component reactions, greatly reducing time and cost involved in the design loop.

Romax Designer Features:

Extremely fast solution times allow many more concepts or detailed designs compared to traditional procedures. In one package, RomaxDESIGNER offers:

Virtual product development tools

Dynamics and NVH

Analyse gear whine behaviour using the same model that you use for durability and rattle analysis

Confidently and accurately predict gear whine vibrations for manual and automatic transmissions at the design stage before expensive mistakes are made

Quickly and easily see the effect of design changes on NVH performance

Troubleshoot problems with existing designs and find solutions in a fraction of the time of traditional methods

Analyse vibration response and dynamic behaviour at component and full system level

Identify root causes of transmission noise via mode shape, modal energy, waterfall plots and harmonic response etc

Perform gear contact analysis for hypoid and bevel gears with interface to ANSol

Accurately account for misalignments and micro-geometry effects giving you accurate data to make design decisions

Optimisation and robustness studies

Perform system sensitivity analysis (DoE) and carry out optimisation experiments

Access all the parameters within the gearbox

Perform robustness studies and design for six sigma


Romax software is optimised to work with the whole design process. A range of interface options are available to enable your integration into your existing design environment. These enable smooth data hand-over to other software tools and provide co-simulation links.
