INFLUENCE OF TRANSMISSION LINE CABLE WITH IN LINE FITTINGS SYSTEM MATRIX EIGENVALUES DETERMINATION ON CABLE FATIGUE LIFE ASSESSMENT
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.
