Przestrzenne drgania elementu prętowo-bryłowego

Wacław Przybyło
In the paper are considered spatial, undamped, free and forced, steady-state harmonic vibrations of a rod-body element – the system composed of a bisymmetric, elastic rod the ends of which are connected with two rigid bodies by means of spatial, weightless supports of both the displacement and rotation types. The loading is assumed to form a system of harmonic state vectors with identical frequencies and phases of vibrations. A matrix-type nonhomogeneous transformation equation is derived, based on the displacement method.
