RomaxDesigner

RomaxDesigner is a virtual product development and simulation environment for the design and analysis of the complete transmission - gearboxes, bearings and drivetrains and all components. The RomaxDesigner environment can be used at the centre of your engineering process, at each stage of the product lifecycle.

Our simulation technology, RomaxDesigner was the world's first object orientated engineering design software and over the last 14 years has been used by major OEMs, component manufacturers and academics across the automotive, aerospace, off-highway, motorsport and rail industries.

System modelling capabilities

• Build custom bearings or select from comprehensive OEM catalogues
• Define custom connections between parts: in all 6 degrees of freedom
• Integrate any type of gear
• Define clutches, belts, chains, torque convertors, synchronisers and variable coupling ratios
• Work with Finite Element components and condense using Romax FE Solver
• Supports parallel, perpendicular and planetary systems
• Model non-90 degree shaft arrangements
• Define parameters for nearly all system attributes and connections

Component analysis capabilities

• Complete component analysis
• Calculate forces, stresses displacements and misalignment
• Design and optimise gear macro- and micro-geometry
• Customise bearings and other materials
• Bearing pre-load tool for pre-load investigation

Dynamics and NVH

• Analyze 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

Interfaces

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.

• CAD interface
• FEA interfaces to Nastran, Ansys, Abaqus, Hypermesh, I-DEAS and RADIOSS
• LDP interface
• ANSol interface
• XML interface
• Catia interface
