Straty mocy oraz ich własności w niskim zakresie warunków pracy silnika elektrycznego robota w kontekście badań efektywności energetycznej

Straty mocy są jednym z wielu czynników wpływających na efektywność energetyczną procesów produkcyjnych, jednak pomimo tego, najczęściej badane zakresy strat mocy nie określają sposobu ich zmian w trybach pracy odmiennych od typowej pracy napędowej. Opisane badania zostały skoncentrowane na niskim zakresie warunków pracy silnika robota przemysłowego oraz na własnościach zmian postaci strat mocy podczas przechodzenia ze stanu pracy napędowej do pracy statycznej. Oprócz wyznaczonych wartości komponentów map mocy, w pracy przedstawiono techniczne rozwiązania umożliwiające wykonywanie pomiarów stanów elektrycznych robota w warunkach przemysłowych, którymi były zniekształcenia, zakłócenia oraz ograniczony zakres pozycji kątowych badanego przegubu robota.

Power losses and their properties for low range of a robot electric motor working conditions as the part of energy effectiveness research

Power losses are one of many factors affecting the energy effectiveness of production processes, however despite this, commonly investigated ranges of power losses do not explain how they change in the stages being different from a typical driving mode. This investigation focuses on low working conditions of a robot electric motor and the properties of power losses changes while going from a driving mode into a stand-still mode of electric motor work. Apart from determined values of power maps components, this work shows how to manage with technical limitations in performing measurements of industrial robot electrical states at the industrial conditions, like high disturbances, noise and limited range of robot axis angle position.

Virtual prototyping of the suspended monorail in the aspect of increasing the permissible travel speed in hard coal mines

Due to the longer distance of moving the crew to the workplace in hard coal mines, the possibility of increasing the maximum permissible speed of suspended monorails was considered. To ensure an adequate level of safety, decelerations affecting the crew in the case of emergency braking in various travelling conditions were analysed. The computational model was verified based on the results of the bench tests on a dedicated test track. The article presents a comparison of results of numerical calculations with measurements at the test stand, and results of numerical simulations in relation to the criterial states that could not bechecked at the test stand as well as the analysis of overloads that affect the crew during the emergency braking. These overloads have a significant impact on safety of the operator and passengers, and their determination and analysis may be the basis for assessing the degree of safety as well as for the development of guidelines for designing the additional equipment for the operator's cabs and passenger cars, i.e. components increasing their safety.
