    Dynamics and control experimental laboratory
    (Wydawnictwo Politechniki Łódzkiej, 2006) Marynowski, Krzysztof; Stefański, Andrzej; Wojewoda, Jerzy; Jagiełło, Bogdan; Red. nauk. Wydziału: Wojewoda, Jerzy; Warmiński, Jerzy; Wiercigroch, Marian
    The book we are proud to present is the effect of many years of experience gathered during teaching the Dynamics and Control at the International Faculty of Engineering in Technical University in Łódź. Dynamics and control are usually two separate subjects in programs of technical studies. The third year of the course of Mechanical Engineering and Applied Computer Science is combined into a single subject. Our over ten years didactic experience shows it gives finally very good results. The manuał contains a set of instructions how to perform 14 laboratory exercises from various issues of dynamics and control. They contain wide theoretical background and already solved exercises helping to complete the given tasks. In fact, the book is intended for students of the third year, but all interested in solving the practical issues of dynamics and automatics also can use it. We appreciate the support extended to us by all our colleagues from the Division of Dynamics of the Technical University of Łódź and gratefully acknowledge the individual help given to us by Małgorzata Jóźwik for careful and proficient translating.

    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.
