Fluid Power-Specific Measurements
The precise analysis of fluid power systems is the key to optimised processes, higher efficiencies and long-term operational reliability. This is not just about measurements, but also about a deep understanding of the physical relationships and the selection of the right methods.
FLUIDON not only provides the necessary expert knowledge, but also supports companies on their way to developing their own high-performance test bed infrastructure. Instead of merely offering measurement services, we focus on enabling our customers to carry out their test processes independently and efficiently by providing them with in-depth advice and simulation-based design.
Our range of services extends from the development of customised measurement concepts to the simulation and optimisation of test stands and the provision of innovative Cube workflows for precise measurement data evaluation and simulation parameter determination.
Input impedance of hydraulic components
The input impedance describes the dynamic termination behaviour of fluid power components and is a crucial parameter for the oscillation behaviour of fluid power line systems. Inaccurate or omitted consideration can lead to unwanted resonance effects, which can negatively impact the functionality and service life of the entire hydraulic system.
FLUIDON offers comprehensive support in the theoretical and experimental determination of input impedance in accordance with ISO 10767-1, the recognised standard method for determining this important characteristic. In addition, we support our customers in all phases of their test bench project:
Our services in the field of input impedance measurement:
- Design and development of customised test bench solutions
- Simulative design of the test stand for precise and reproducible measurement results
- Support during the construction and commissioning of the test stand
- Implementation of efficient measurement strategies for standardised recording of the input impedance
- Development of dynamically equivalent replacement models to precisely map components in the simulation
- Training and support with data interpretation
Understanding the transfer behaviour of hydraulic components
Every hydraulic component has a unique transfer behaviour that describes how it behaves at different frequencies. A false estimation can lead to the creation of resonances or insufficient vibration damping.
FLUIDON can help you to better understand and optimise the dynamic behaviour of your components by experimentally and simulatively determining the transfer matrices. With our four-pole analysis technology, even complex hydraulic components can be measured. We advise you on the selection of suitable measurement technology and support you in integrating the measurement method into your development processes.
Our services include:
- Design and development of customised test stand solutions
- Simulative design of the test stand for precise and reproducible measurement results
- Support with the construction and commissioning of the test stand
- Workflow creation for automated measurement data processing
- Integration of the transfer behaviour into the system simulations
Measure and evaluate volume flow pulsations
Hydraulic pumps and motors inevitably generate volume flow pulsations that can affect the entire system. These pulsations are often an underestimated source of pressure fluctuations and unwanted oscillations that can impair system performance or even cause component damage.
FLUIDON can help you develop and optimise test stands that can accurately capture volume flow pulsation. With the help of anechoic line termination technology (RaLa), we minimise measurement errors caused by reflections, so you get reliable and realistic measurement results.
Our expertise can help you:
- Characterise sources of pulsation at an early stage
- Avoid oscillation problems before they occur
- Improve system designs to achieve optimal operating characteristics
Flow measurement of pneumatic resistances
Knowledge of pneumatic resistance values, such as the critical pressure ratio and the pneumatic conductance, is crucial for the realistic simulation of pressure losses in pneumatic systems. Incorrect parameterisation can lead to inefficient energy use and unpredictable behaviour.
FLUIDON offers comprehensive advice on how to measure pneumatic resistance in accordance with ISO 6358.
Our services include:
- Design and development of efficient test stands for flow measurements
- Determination of critical pressure ratio and pneumatic conductance
- Comparison of real component properties with simulation results
