EZE -Easy zonal hydraulics
- Project code:EZE
- Schedule:1.5.2019 - 30.4.2021
- Status:finished

FIMA is jointly participating in a new research project with several Finnish companies. The backround of the project is last year completed EL-Zone.
The target is to study and develope knowledge on zonal hydraulics in the following focus areas:
- System architecture: to apply new easy electro-hydraulic system architectures and dimensioning of high-energy efficiency and high performance to increase the power (capacity, economy and ecology) of the mobile machine application
- Ease of installation and commissioning
- Component selection routines/tools based on efficiency maps
- Operating requirements, benefits and restrictions
- System diagnostics, condition monitoring and forecasting pending failures (incl. IoT and digital twins)
- Knowledge base for compiling safety standards for EHA/DDH systems/units
