Design without Compromise
RomaxWIND is a virtual product development and simulation environment for the design and analysis of wind turbine gearboxes, bearings and drivetrains and is used by wind turbine gearbox manufacturers, wind turbine system providers and wind turbine owners/operators across the globe.
Designed to add value, its use can reduce costly design iterations, develop robust products and facilitate a unique understanding of component and system behaviour. RomaxWIND can simultaneously model and analyse bearing deflection, shaft misalignment, spline deflection, gear mesh misalignment and housing deflection to create an all-in-one analysis.
RomaxWIND
RomaxWIND is the industry specific package of RomaxDesigner, the world’s first object orientated engineering design software. With 20 years of experience across industry and a proven track record of working with the world’s largest engineering companies, Romax is a trusted global partner.
RomaxWIND as part of your design process
RomaxWIND is built entirely in-house and uses non-linear bearing stiffness representation which is written and tested by Romax, and validated with external customer data. Our design process has been tried and tested across industry and adopted by some of the world's leading OEMs.
Benefits of using RomaxWIND
Designing with RomaxWIND gives a great many advantages to wind turbine system and gearbox, bearing and drivetrain designers, these include:
Decreased design time compared to existing tools
Review concepts easily and quickly – all permutations can be considered
Easy swap of components and view their impact on performance, weight, manufacturing – the switch of a helical gear for a spur gear for example
Reduction in analysis times of all interacting components
Analysis cycles reduced – multiple load cases can be set up and run in conjunction to save time, without reducing the effectiveness of the analysis
Analyse the behaviour of complex planetary systems within the whole system
Usability
View the gearbox as one complete system, without the need for sectioning and sectional boundary conditions
Understand and benchmark operating load and extreme load scenarios
Understand the forces and material capabilities enables design decisions to be made before expensive prototyping is performed, ensuring quiet, durable, long lasting components
Load predictions & calculations
Accurately predict loads, deflections and interactions of all components
Calculate detailed bearing behaviour to identify excessive loads
Direct loads or reduce misalignments to improve the system quality
Predict load sharing in the fully flexible system instead of assuming load sharing factors
Cost savings
Reduce weight and cost without reducing component lifetime
