Abstract
The article provides a brief description of the program Dynwir-S-70 (currently being developed in the Rotor Dynamics and Slide Bearings Department in the Institute of Fluid-Flow Machinery Polish Academy of Sciences in Gdansk) which is a program for analysis of multi-supported and multi-mass rotors. Used algorithms and the construction of mass and stiffness matrix were presented. Damping matrix structure based on Rayleigh damping was presented. The article also shows the influence of alpha and beta factors on form and frequency of proper vibrations of rotors. Results of the author’s program were compared with the commercial program Madyn 2000.
