Hydraulic Accumulator
Hydraulic accumulators are installed in numerous HS for various tasks, but mostly to add pressurized hydraulic liquid (HL) in HS. In some HS, a large, far above-average amount of pressurized liquid HL is required…
Human-Machine Interaction in Industry 4.0 and Beyond
Manufacturing represents around 15% of the value-added and total employment in Europe. It is also of great importance to the EU and its R&D efforts, to which almost two thirds is contributed by manufacturing.
Advanced data-based methods for fault detection in HVAC systems
Fault detection in industrial systems plays a crucial part of the correct and optimal operation of the different processes. The possible faults could be of different types and natures and occur on different components of the process.
Agile development of complex mechatronic systems
Today’s fast paced and ever changing market dictates perpetual variations in product requirements already during the product’s development process. If the involved design teams aren’t capable of taking these variations…
Multicriteria optimization model for polymer gears
The design of polymer gears is a demanding process due to the multitude of interconnected material, geometric and operational parameters, which together form a very complex system for analytical treatment.
Comparison of standard test particles with real ones from hydraulic filters
In the first part of the paper we present the reasons for the occurrence of particles in a hydraulic fluid. The problem of using a standardized test dust due to its abrasiveness, which is much …
Web Controlled Pneumatic Press
The article describes a web controlled pneumatic press as an example of a system designed to demonstrate the control of pneumatic devices via the Global Area Network (GAN).
Distance Learning Opportunities. Will we be Able to Use Them in Future?
When the situation with COVID-19 demanded closing nursery schools, primary and secondary schools, high schools, universities and colleges, and therefore demanded distance learning, the situation seemed complicated.
Multicriteria approach to polymer gear design
Reliable polymer gear design remains to date an open challenge due to a lack of data regarding the specific properties of polymer materials and due to complex relationships between the gears’ geometric parameters and the applied running loads.
Analysis of real and test particles in hydraulic filters – 1st part
In the first part of the paper, the reasons for the appearance of particles inside the hydraulic liquid are presented. These are the four possible types of wear, two-body abrasive wear, three-body abrasive wear, erosion and cavitation.
