Romax: Designing Better Transmissions | Durability, Noise & Efficiency

How do you design a transmission that is durable, quiet and efficient? Start by understanding how its gears, bearings, shafts and housing work together. In this SIMTEQ Engineering Sharpen the Saw session, Marceliano Fumero explores Romax’s system-level approach to transmission design and analysis. Discover how component interactions, load distribution and structural deflection influence performance—and why analysing individual components in isolation can miss important design considerations. The session follows the development process from early transmission concepts to detailed analysis and optimisation, showing how engineers can investigate competing requirements within a connected simulation workflow. Topics covered: Concept development: Explore transmission layouts, packaging constraints and preliminary design comparisons with Romax Concept, before introducing system flexibility during detailed analysis. Durability and component design: Understand how gear geometry, bearing selection, loading and deflection influence contact patterns and component performance. Noise, vibration and acoustics: Investigate transmission error, gear whine, structural vibration and sound radiation from the transmission housing. Efficiency and power losses: Examine gear and bearing losses under operating conditions and include efficiency objectives in the wider design process. System optimisation and lightweighting: Explore the trade-offs between durability, noise, efficiency and gearbox weight, including the effects of increased flexibility. Who should watch? This session is suited to engineers with a CAE background who want an introduction to Romax and its applications in transmission and driveline development. No previous Romax experience is assumed.
