    The paper presents the initial investigation of possible energetic applications of chosen wastes from groups: 06, 13, 05 and 01. The change of combustion heat value was evaluated in produced energetic mixtures together with the change of their individual components. Furthermore, the application of regressive method was proposed in purpose of calculating combustion heat value and then the comparison of empirically determined and theoretically calculated heat values was performed.W artykule przedstawiono wstępne badania nad możliwością energetycznego zagospodarowania wybranych odpadów z grup: 06, 13, 05 i 01. Oceniano zmianę wartości ciepła spalania w utworzonych mieszankach energetycznych wraz ze zmianą w nich udziału poszczególnych komponentów. Zaproponowano także wykorzystanie metod regresji w celu obliczenia ciepła spalania, a następnie dokonano porównania ciepła wyznaczonego empirycznie z obliczonym teoretycznie

    Influences of system parameters on energy harvesting from autoparametric absorber. Experimental research

    No full text
    In the paper an experimental analysis of an autoparametric system dedicated to vibration suppression and energy recovery is presented. The main part is an electromagnetic energy harvester. Its properties were defined by quasi static and dynamic tests. The obtained results show influence of selected parameters on energy recovery level. The experimentally identification of electromechanical coupling coefficient which couples mechanical and electrical systems is done

    Influences of system parameters on energy harvesting from autoparametric absorber. Numerical research

    No full text
    In the paper a numerical analysis of an autoparametric system is presented. The two main elements of a tested system are the pendulum (tuned mass absorber) and an energy harvester. The electromechanical model takes into account these both effects. Numerical simulations are made in a MATLAB software environment. The obtained results allowed estimation of influence of the system parameters on efficiency of energy harvesting
