The main of this paper is to study the microstructure and physical properties of the Fe75B10Si10Cr5 in condition after being produced. The sample was prepared as cylindrical rod with a diameter of 3 mm. The rod was produced using the arc melting method with a suction casting option. It was found that produced alloy was nanocrystalline with average grains of about 15 nm. Due to the different cooling...
The research comprises a discussion about a formation of intermetallic phase with stoichiometric composition Fe2Ti, called Laves phase, and influence of chromium on the whole structure containing this phase by means of comparison of the two alloys. A base Fe35Ni35Ti30 alloy was used as a reference and then compared with a Fe-Ni-Ti chromium doped - Fe30Ni35Ti30Cr5 alloy. The study of microstructure...
In this work the authors present the properties of the Fe59Mn27Ni7Cr3Si4 (at. %) shape memory alloy. Two different phases were discovered during the XRD analysis and Fe-Mn phase was identified. The hardness of the investigated material in the as-cast state was 194 HV. The nano hardness was 511 HV and Young modulus was determined as 159 GPa. AFM and LFM tests allowed to observe linear arrangement of...
Przedmiotem pracy są badania symulacyjne mechanizmu wspomagania rehabilitacji kończyn górnych MWR. W artykule przedstawiono przegląd istniejących rozwiązań urządzeń wspomagających rehabilitacje oraz wskazano zasadność podjęcia tematu badawczego. Ponadto wykonano analizę dynamiczną w celu określenia sił oddziaływania w parach kinematycznych oraz momentów czynnych w napędach.
SLAM jest to algorytm równoczesnego mapowania otoczenia i lokalizowania się na tworzonej mapie. Wykorzystywany jest w robotach autonomicznych przeznaczonych do pracy w nieznanym bądź dynamicznie zmieniającym się otoczeniu. W swojej podstawowej formie wykorzystuje czujnik odległości, taki jak lidar bądź radar oraz dane o przesunięciu pozyskiwane z enkoderów. Dzięki zastosowaniu odpowiednich strategii...
