Prykladni Problemy Mekhaniky i Matematyky| Summary: | On the example of the problem of free longitudinal vibrations of a beam free at one end and fixed at the other end the error of vibration process approximation by third-degree Beta-splines is examined. The error is calculated by comparing the obtained solution with the solution of Fourier. The error dependence on node net by the beam length as well as on the step of time partition of the vibration process is obtained. The high convergence of the spline collocation method is shown.
