The purpose of the study is demonstration of the possibility of identification of boundary conditions in an ill-posed problem. The problem is understood as determination of four constants necessary for a description of functions of forced vibration amplitudes from three equations. To this end, the Singular Value Decomposition (SVD) algorithm is used. After determining the amplitudes of forced vibration,...
Jak powszechnie wiadomo, drgania wywoływane przez pracujące urządzenia mają niekorzystny wpływ na warunki ich eksploatacji. Jedną z metod obniżenia częstotliwości i amplitudy drgań jest modyfikacja struktury układu. W pracy [6] przedstawiono wpływ modyfikacji strukturalnej belki, w postaci dodatkowej masy skupionej, na jej drgania własne. Dodatkowa masa skupiona powoduje obniżenie pierwszej częstości...
