The harmonic balance method for determining the vibration parameters in damped dynamic systems

Abstract The object of the paper is to present a method of analysis of forced vibration of discrete mechanical systems, taking into account Coulomb friction forces at the dampers. The method relies upon assuming the solution in the form of a Fourier series and applying the harmonic balance method. The approach described in the paper can be used for vibration analysis of gas and steam turbine blades and blades of axial compressors. The analysis is provided with an algorthm and an example of calculations. There is a description of the computer program which was utilized during the calculations.
