Romax WIND - Wind Turbine Gearbox and Drivetrain Design Software
Our unique software, RomaxWIND, enables you to create and analyse drivetrain systems and gearboxes, and then accurately simulate their behaviour and performance to ensure you get the optimum final design.
Software Overview
RomaxWIND is used from the early stages of the detailed design phase and can model and analyse bearings, shafts, splines, gear meshes and housing simultaneously to create an all-in-one system model. Its flexible full-system model means that components can be designed with confidence to be low cost, lightweight, efficient and durable. In addition, RomaxWIND's proven noise and vibration analysis capability can eliminate almost all dynamic issues before hardware is created. When used alongside Dynamic FUSION, RomaxWIND provides an efficient, easy to use solution able to satisfy all of the dynamic requirements required for certification.
- Nine major wind energy manufacturers use Romax multi-megawatt designs
- 38 wind gearbox designs using Romax software have received certification from industry bodies within a four-year period
- RomaxWIND is the only engineering software awarded DNV GL certification for its gear and shaft calculation methods and reporting

- System deflection and forces predicted including thermal expansion
Results visualisation
- Results visualised as a 2D or 3D view
- Calculation of component and system reliability, based on variability of load and material strength
- Gear mesh misalignment classification, gives component level contribution to the predicted misalignment
What It Dones
A virtual product development and analysis environment for the design and simulation of wind turbine gearboxes and drivetrains, RomaxWIND is a used by wind turbine gearbox manufacturers, wind turbine system providers and wind turbine owners/operators across the globe.
Designed to provide a unique understanding of component and system behaviour, it can reduce development timescales and costly hardware iterations through a Right First Time™ design approach.
RomaxWIND also works seamlessly with Romax CONCEPT, CAD FUSION and Dynamic FUSION software to support wind turbine driveline development from concept through to certification and production. It is used from the early stages of the detailed design phase and can model and analyze bearings, shafts, splines, gear meshes and housings simultaneously to create an all-in-one system model.
By combining the latest component rating standards with this flexible full-system model, components can be designed with confidence to be low cost, lightweight, efficient and durable. In addition RomaxWIND’s proven noise and vibration analysis capability can eliminate almost all dynamic issues before any hardware has been created. When used alongside Dynamic FUSION, RomaxWIND provides an efficient, easy to use solution able to satisfy all of the dynamic analysis requirements needed for DNV GL certification.
An area where RomaxWIND is continuously finding new customers is fault diagnosis and troubleshooting of existing designs, where highly detailed analysis methods are able to reproduce and rectify of real world issues.
Benefits
