Efficiency is a performance target of significant interest in most industries, due to its impact on environmental targets and fuel costs. In transportation, for example, power losses have a direct impact on range. Increasingly strict legislation further enforces efficiency requirements on suppliers.
Full System Efficiency
- Efficiency is a complex function of many speed and load dependant power loss contributions within the transmission.
- System level calculation includes, local powers at each component together with the cascading effect of component losses through the system.
- Easily and quickly generate transmission efficiency maps.
Calculating Efficiency, More Efficiently
- For an effective design tool fast but sufficiently accurate calculations of the different power loss components are required. For each component there are many such power loss calculations used in the industry which are empirically or semi empirically derived.
- Different companies use different formulations, choosing those which best match their test and field experience. Further, many companies develop empirically calibrated modifications to existing formulations based on their own testing.
- MASTA provides a unique, flexible solution to full system level efficiency simulation.
- MASTA includes many inbuilt options for power loss calculation of each component to methods such as those in ISO 141479 and many other methods in the literature.
- Further, a unique scripting solution allows users to modify component power loss calculations and include their own modifications or complete calculations within MASTA’s system efficiency simulation.
- This provides a truly customisable system level efficiency simulation enabling users to include their own experience and IP gained over many years.
Advanced Efficiency Calculations
- Higher fidelity calculations of component power loss are also included
- Higher fidelity gear mesh loaded loss calculations based on Loaded Tooth Contact Analysis, including the impact of micro geometry on losses.
- High Speed Bearings – Accurate calculation of bearing power losses, particularly in nonstandard operating conditions where the standard calculations do not apply
Efficiency Optimisation
- Optimisation for efficiency can be achieved via Parametric Study Tool, scripting and batch running capabilities. Quick studies to quantify the effect of tolerances and design changes
- Easily identify the main contributing components to overall power loss in different operating conditions and target design changes
