Create efficient drivetrain designs
With Romax Energy, efficiency is at the forefront of the drivetrain design process. Optimized with proven and accurate analysis methods that reduce reliance on physical prototyping, Romax Energy can help reduce development costs of sustainable designs. The key benefits of using Romax Energy include:
Benefits And Features
Master drivetrain efficiency prediction
Predict power losses early
Calculate transmission power loss, energy, fuel consumption and emissions using widely used industry methods and our proprietary drag models.
Account for lubricant effects
Accurately predict a lubricant’s effect on system efficiency, based on FVA345 methodology, and select or design the optimal oil.
Quickly assess parameters
Conduct parametric studies to investigate the impact of numerous variables, such as torque, speed, temperature and lubricant levels on system efficiency.

Frequently Asked Questions
We already have Excel spreadsheets to solve the ISO standards for efficiency. Why do we need this?
Using Romax Energy alongside other Romax products, means that efficiency can be optimized in a single model alongside durability and NVH.
Evaluating losses as part of a system-level static analysis improves accuracy and helps improve understanding of power flows through complex systems.
In addition to the ISO standards, Romax Energy offers proprietary advanced loss models for gears and bearings, that capture a lot more effects (e.g. bearing misalignment, detailed geometry, and lubricant traction properties).
CFD analysis takes too long to run, and doesn’t match test results
Meshless CFD tools such as Particleworks are very good at predicting trends, so are well suited for what-if design studies at an early stage (e.g. effect of fill depth on churning loss). The interface from Romax Energy to Particleworks reduces the time taken to build a functioning drivetrain model in CFD, making it easier to include CFD within design studies.
