Sažetak
Fatigue of cable strands is the most common form of damage resulting from Aeolian vibra-tions and it occurs at points where motion of cable is constrained against transverse vibra-tions. The first and crucial step of applying Modified Energy Balance Method (usually used for transmission line Aeolian vibration response analysis) is accurate determination of the system eigenvalues. A numerical procedure that searches for parameters s that make system matrix J(s) of transmission line cable with in-line fittings (Stockbridge vibration dampers, spacer-dampers, aircraft warning spheres) singular is considered in this paper. Presented numerical example illustrates advantages of the developed numerical procedure.
