    • Fundamental Research on Hydraulic Systems Driven by Alternating Flow 

      Autor: Marcu , Ioan-Lucian; Banyai , Daniel-Vasile
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      This paper presents a new approach to rotary hydraulic systems, and the functional principles of rotary hydraulic systems that can work using alternating flows. Hydraulic transmissions using alternating flows are based on ...

    • Influence of Various Process Parameters on the Density of Sintered Aluminium Alloys 

      Autor: Laska , Mateusz; Kazior , Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      This paper presents the results of density measurements carried out on Alumix sintered parts. ECKA Alumix aluminium powders were used because of their wide application in the powder metallurgy industry. The compacts were ...

    • The Simulation of the Influence of Water Remnants on a Hot Rolled Plate after Cooling 

      Autor: Zahradník , Radek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      In situations when a sheet metal plate of large dimensions is rolled, water remnants from cooling can be observed on the upper side of the plate. This paper focuses on deformations of a hot rolled sheet metal plate that ...

    • Holding Pressure and Its Influence on Quality in PIM Technology 

      Autor: Petera , Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      The PIM (powder injection molding) process consists of several steps in which faults can occur. The quality of the part that is produced usually cannot be seen until the end of the process. It is therefore necessary to ...
