    • An assessment of thermo-mechanically induced fatigue damage of a steam turbine shaft 

      Autor: Nesládek M.; Jurenka J.; Lutovinov M.; Růžička M.; Měšťánek P.; Džugan J.
      (Elsevier B.V., 2017)
      The increasing demands on the flexibility of steam turbines due to the use of renewable energy sources substantially alters the fatigue strength requirements of components of these facilities. The work summarized hereafter ...

    • Development of composite energy absorber 

      Autor: Růžička M.; Kulíšek V.; Bogomolov S.; Sháněl V.
      (Elsevier, 2014)
      This paper presents experimental investigation and numerical prediction of the deformation behaviour of several types of composite deformation elements, whose potential use is in public passenger transport. Experiments ...

    • Influence of Composite Spindle Ram on Machine Tool Dynamic Stiffness 

      Autor: Kulíšek V.; Kolář P.; Smolík J.; Růžička M.; Janota M.; Machálka M.
      (MM Science Journal, 2022)
      Demands for improving machine tool productivity and accuracy can be addressed using alternative material structures with the potential to reduce the mass of moving bodies and decrease machine tool dynamic compliance. A ...

      (Bertelsmann Media, 2014)
      Článek popisuje možnosti zvyšování užitných vlastností obráběcích strojů aplikací vláknových kompozitů, které mohou přispět k snížení hmotnosti komponent a zvýšení jejich tlumení. Jsou analyzovány základní mechanické ...

    • Numerical simulations of fatigue crack growth in a steam turbine rotor blade groove 

      Autor: Kuželka J.; Nesládek M.; Lutovinov M.; Jurenka J.; Růžička M.; Rund M.; Měšťánek P.
      (Elsevier B.V., 2019)
      With increasing share of renewable energy sources in the electricity production strict demands are placed on thermal power plants that have to cover the power shortages more frequently. Increasing number of steam turbine ...

    • On passive damping in machine tool hybrid structural parts 

      Autor: Kulíšek V.; Kolář P.; Vrba P.; Smolík J.; Janota M.; Růžička M.; Machálka M.
      (Springer, 2021)
      Hybrid materials combining steel or cast iron with fibre or particle composites have a good potential for lightweight machine tool structural design with high damping ratio. These materials are analyzed in the paper with ...
