  • Vibration equations of contact wires were used to derive the formulae for calculation of mean and standard deviations of stresses.Statistical characteristic of fatigue strength of contact wires was obtained by comprehensively considering such coefficients as stress concentration,size and surface quality.A mathematic model for fatigue reliability of contact wires was presented based on statistical principle.Analyses results show that the materials,tension and rigidity of wires,speed of trains,wave speed,and lift forces are primary factors that affect fatigue life of contact wires.
