Abstract
Increasing performance in modern hydraulics is achieved by a close investigation of possible enhancements of its components. Prior research has pointed out that electromechanical actuators can form suitable alternatives to hydraulically piloted control systems. Since the requirements at these actuation systems depend on the operating conditions of the system, each actuator can be optimized to the respective hydraulic system. Considering that many different conceptual designs are suitable, the phase of conceptual design plays a decisive role during the design process. Therefore, this paper focuses on the process of developing new conceptual designs for electromechanical valve actuation systems using the method of function structures. Aiming to identify special design features, which need to be considered during the design process of electromechanical actuation systems, an exemplary actuator was designed based on the derived function structure. To highlight the potential of function structures for the development of new electromechanical valve actuation systems, two principal concepts, which allow the reduction of the necessary forces, have been developed by extending the function structure. These concepts have been experimentally investigated to identify their advantages and disadvantages.
Highlights
Splitting the system into its generally valid functions allows optimization not restricted to just the reduction of flow forces, which has previously been an effective approach to reduce the necessary forces of valve actuation systems
Since the design of the actuator according to the necessary forces and strokes depends on the considered application, each actuator should be tailor-made to the corresponding system
The presented paper is intended to provide a general basis for the design of novel valve actuators and focuses on the phase of conceptual design, as well as the identification of basic design features of electromechanical actuators, rather than on the dimensioning of the electromechanical transducer
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Most large-sized control valves are operated via smaller pilot valves. This type of actuation is characterized by high attainable forces over large possible strokes. In order to impress sufficient forces and, ensure a reliable switching process, a minimum working pressure difference over the valve of approximately
