The master's thesis deals with the dynamic and strength analysis of the cross-cutting saw, a machine used to cut insulation boards in the process of mineral wool production. The creation of a dynamic model for a new generation of the cross-cutting saw is presented. Modal analysis was used to determine the machine's natural frequencies, which highlighted the incorrectly dimensioned saw flange. The most demanding operating conditions of the machine were determined. A multibody simulation, which employed substructuring using component mode synthesis methods, was done. Areas of critical stresses and their magnitudes were determined, and the effect of the machine's acceleration was studied. We suggested potential improvements of the machine design. Additionally, the oscillation of the saw blade during operation was analysed and determined to be within the required tolerances.
