Application of the rigid finite element method to modelling of free vibrations of a band saw frame

The paper presents an application of the rigid finite element method to modelling of the arm of a band saw. The equations of motion are derived using the Lagrange equations and methods used in analysis of multi-body systems. The method presented enables interactions between the base and the frame to be taken into account. The influence of flexibility of some elements of the band saw on natural frequencies is shown.
