Water-hydraulic endurance test of an oil-hydraulic proportional directional control valve
Hydraulic fluids made from fossil fuels are a major ecological burden despite their good corrosion and wear properties. Water seems to be the future of hydraulic fluids, but due to lack of interest and special equipment, it is still underestimated.
Mathematical Model to calculate the Volume of Hydraulic Accumulator
Hydraulic accumulators (HA) are installed in numerous HS mostly to add pressurized hydraulic liquid (HL) in HS to compensate the disproportionate consumption of some working hydraulic components…
Scientific Commentary of the Particulary Criminal Code – Penal Acts against the Safety of the Public Traffic
Slovenia has got the Scientif Commentary of the Particular Criminal Code – Penal Acts against the Safety of the Public Traffic.
Determination of static sensitivities of fast-response pressure measurement systems
This paper presents a dynamic and quasi-static method for determination of static sensitivity of fast-response piezoelectric pressure measurement system. In order to establish SI traceability for time-varying pressure measurements…
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 …
