  • Lykhachova, Olga; Kołakowski, Zbigniew (Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics.Wydawnictwo Politechniki Łódzkiej. Wydział Mechaniczny. Katedra Dynamiki Maszyn., 2016)
    Buckling problem of pressured shallow spherical shells is studied numerically for two types of finite elements: axisymmetric and non–axisymmetric. A very good correspondence of obtained results and known solutions is ...

  • Kuźma, Patrycja; Kapitaniak, Marcin; Kapitaniak, Tomasz (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2014)
    We consider the coupling of multistable nonidentical systems. For small values of the coupling coefficient the behavior of the coupled system strongly depends on the actual position of trajectories on their attractors in ...

    The influence of the grinding process on the condition of the surface layer (SL) obtained by the treatment of the gear with grinding wheels Al2O3, CBN, GF, SG, alloy steels with different parameters of the grinding process ...
  • Teter, A.; Kołakowski, Zbigniew (2012)
    In this paper the analysis of the damping behaviour of thin-walled composite columns with open stiffened cross-sections subjected to in-plane pulse loading is described. The pulse loading of a rectangular shape is ...
  • Awrejcewicz, Jan; Starosta, Roman; Sypniewska-Kamińska, Grażyna (2014)
    The dynamic response of a nonlinear system with three degrees of freedom, which is excited by nonideal excitation, is investigated. In the considered system the role of a nonideal source is played by a direct current motor, ...

    The article presents a development of numerical model for a single propeller simulation and comparison of obtained results with experimental data available from a test campaign in scale 1:1. Described simulation is a steady ...
  • Lajmert, Paweł; Kruszyński, Bogdan; Sikora, Małgorzata; Ostrowski, Dariusz (Stowarzyszenie Inżynierów i Techników Mechaników Polskich, 2014)
    W procesie monitorowania szlifowania kłowego wałków może być rejestrowanych szereg sygnałów pomiarowych takich jak składowe siły szlifowania, sygnały drgań, czy emisji akustycznej. W artykule porównano różne metody ...
  • Dudkowski, Dawid; Maistrenko, Yuri; Kapitaniak, Tomasz (2014)
    We discuss the occurrence of chimera states in networks of nonlocally coupled bistable oscillators, in which individual subsystems are characterized by the coexistence of regular (a fixed point or a limit cycle) and chaotic ...
  • Wajszczyk, Piotr (Wydawnictwo Uniwersytetu Łódzkiego, 2015)
    There is an ongoing investigation by scholars of ethics and economics into whether human decision making and the resultant acts should be guided by rules and proce-dures or by judgment and discretion. Although each of these ...
  • Pawłowski, Witold; Bojanowski, Sebastian (2014)
    W artykule przedstawiono procedurę dostrajania wirtualnego modelu (cyfrowego prototypu) wrzeciennika ściernicy szlifierki do otworów. Dostrajanie wykonano, przeprowadzając eksperymentalne badania statyczne oraz identyfikacyjny ...
  • Sypniewska-Kamińska, Grażyna; Starosta, Roman; Awrejcewicz, Jan (Politechnika Łódzka. Wydział Mechaniczny. Katedra Automatyki, Biomechaniki i Mechatroniki., 2015)
    The externally excited and damped vibrations of the double pendulum in the vertical plane are considered. The pendulum can collide with a rough obstacle many times during its motion. The pendulum is modeled as a piecewise ...
  • Ferdynus, M.; Kotełko, M. (Wydział Mechaniczny. Katedra Wytrzymałości Materiałów i Konstrukcji. Politechnika ŁódzkaLodz University of Technology. Faculty of Mechanical Engineering. Department of Strength of Materials and Structures, 2015)
  • Cedrowska, Agnieszka; Marynowski, Krzysztof (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2012)
    Theoretical and experimental dynamic analysis of an axially moving wide composite web is presented in this paper. The mathematical model of the system under consideration has the form of a differential equation with partial ...
  • Cink, Jacek; Kosucki, Andrzej (Lodz University of Technology. Faculty of Mechanical Engineering. Department Division of Dynamics.Wydawnictwo Politechniki Łódzkiej. Wydział Mechaniczny. Katedra Dynamiki Maszyn., 2016)
    The paper contains the proposal how to reduce many–elements plane mechanism with one degree of freedom to chosen axis or line as one–element model of mechanism. Mostly the place of reduction is driving element in rotary ...
  • Czechowski, L. (Wydział Mechaniczny. Katedra Wytrzymałości Materiałów i Konstrukcji. Politechnika ŁódzkaLodz University of Technology. Faculty of Mechanical Engineering. Department of Strength of Materials and Structures, 2015)
    The work dealt with the numerical simulation of functionally graded plate under thermal pulse loading. It was stated that the great influence on the plate response had the distribution index, the duration and the kind of ...
