Feasibility studies
Simulation technology offers excellent opportunities for putting your new ideas to the test at a very early stage of development. You will quickly gain an impression of whether planned functionalities can be realised with the required quality and in compliance with the given boundary conditions.
Using simulations to investigate the potential for improvement with development variants can help to optimise your products at an early stage. When carrying out these studies, you benefit from our expertise and experience drawn from numerous applications in mechanical engineering and system engineering.
Requirements analysis
We will be happy to help you analyse your drive task in detail in order to determine clear requirements for the drive system, control system and closed-loop control system. This includes both stationary properties of the components involved (flow rates, torques, forces, hystereses, response sensitivities, characteristic maps etc.) as well as dynamic requirements such as the required behaviour in the time and frequency range or the signal transmission rates of digital control units.
If necessary, additional boundary conditions such as performance limits, efficiency specifications, safety requirements, environmental conditions and
signal communication standards are also taken into consideration.
Drive design
Which drive concept is suitable for my application? This question isn't always easy to answer. Modern drive technology often offers a vast number of possible solutions for one and the same drive task. Numerous circuit variants each offer specific advantages and disadvantages in relation to your movement requirements which need to be weighed up against each other. Here is just a small selection of circuit variants for controlling movements, forces and power:
Valve-controlled drives, drives with variable displacement pumps, electromechanical drives, load sensing systems, hybrid drives, variable-speed pump drives, secondary controls, mobile open and closed centre drives, recuperative energy solutions, etc.
Optimising drives and machine functions
We use state-of-the-art methods and development tools to design, analyse and optimise hydraulically or electrically operated machines. In our calculation models, we can take into account the drive behaviour, the properties of the driven mechanics (machine), the complete process control and any external influencing factors. These types of models are extremely informative and, as virtual test benches, can supplement or even replace numerous hardware tests.
Developing high-quality closed-loop control concepts
The hardware and software components for the electronic control of process variables are of great importance for high-quality implementation of machine functions.
Optimally tailoring control algorithms to the physical properties of the machine can significantly improve properties such as stability, control accuracy or the dynamics of movement processes. The aim here is to ensure optimum interaction between the sensors, signal processing, closed-loop control concept and actuators, and perfectly harmonise numerous influencing parameters.
In the field of closed-loop control technology, we have many years of experience in projects from all kinds of industries. We would be happy to use our capabilities to support you with challenging projects.
Efficiency studies and energy analysis
Energy consumption and efficiency are now among the most important and competitive differentiators of machines and systems. These properties should be known at an early stage of development to enable timely corrections and improvements.
The drive structures and all the components involved (motors, converters, batteries, valves, pumps, cylinders, pipework systems, accumulators, coolers etc.) should be carefully matched to the machine's target performance balance. In this context, we compile performance balances and efficiency maps for your systems at specific operating points in order to derive approaches and strategies for optimising energy consumption where possible.
Developing digital twins
Whenever simulation models need to communicate with electronic hardware components (in virtual test machines for control systems, for example) or when people interact with computational models using suitable operating elements (such as driving simulators, virtual reality), the simulation needs to portray the corresponding processes in real-time.
Performing simulations of this type requires specialised expertise which we are happy to provide you with.
Technology training
Servo hydraulics and proportional hydraulics are some of our key areas of expertise. If you would like to get to grips with this interesting but challenging subject area, we offer training events and workshops specially tailored to your requirements.
The following topics are covered, among others, although the content can be customised and expanded to meet your specific needs:
- Circuit types for electrohydraulic drives
- Dimensioning drive components
- Stationary and dynamic drive behaviour
- Control concepts and controller parameterisation
- Optimising drive behaviour
