    Non-linear vibrations of the axially moving paper web.
    (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2008) Marynowski, Krzysztof
    Non-linear vibrations of the beam-like model of an axially moving paper web with time-dependent tension have been investigated in this paper. The considered paper parameters have been determined experimentally. The beam model material is considered as the Kelvin-Voigt element. The Galerkin method and the 4-th order Runge-Kutta method have been used to solve the governing non-linear partial-differential equation. The effects of the transport speed, tension perturbation amplitude and internal damping on the dynamic behaviour of the system have been numerically investigated.

    Dynamic behavior of an axially moving wide web.
    (Polskie Towarzystwo Mechaniki Teoretycznej i Stosowanej, 2012) Cedrowska, Agnieszka; Marynowski, Krzysztof
    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 derivatives. The approximate solution using the extended Galerkin method has been determined in this work. Dynamic analysis allowed one to determine the natural frequency of bending and torsional vibrations of the web. Experimental investigations of dynamic behavior of the axially moving web was performed on a laboratory stand in the form of belt transmission. The experimental verification of numerical studies concerned the lowest frequencies of bending and torsional vibrations. The fundamental frequency of bending vibration was determined numerically with the greatest accuracy. accuracy.
