Subjects: Frequencies of oscillating systems, Mode shapes, Eigenvalues
Abstract: The paper presents the modifications of the eigenvalues for a continuous beam with three spans, free at the ends. The analysis model studied is based on Euler-Bernoulli's theory of the continuous medium. By imposing the boundary conditions for each characteristic point of the beam and solving the resulting system of equations the characteristic relationship was established analytically, whose solutions represent the eigenvalues for the calculation of natural frequencies and the vibration mode shapes. For the first six vibration modes, the modifications of the eigenvalues are illustrated in 3D format, considering that the intermediate supports can occupy any position on the beam.
