Benefits
Meet efficiency targets by changing the design quickly, accurately and reliably, using Romax Energy’s comprehensive efficiency models to predict power losses
Design and optimise components for highly efficient designs by investigating and understanding the impact of varying geometric and operational parameters on the whole system performance
Accurately predict losses and the impact of the oil additive pack and friction modifiers on system efficiency, using our advanced tribological models and proprietary methods based on FVA345 methodology
Component and system-level design for optimal efficiency:
Parametric study to investigate the impact of parameters (e.g. torque, speed, temperature, lubricant level) on system efficiency.
Calculate component power loss using widely-used industry methods and our own world-leading proprietary drag models.
Investigate gear and bearing efficiency and redesign accordingly.
