The Application of ANSYS Stress Concentration Analysis Technique to Etch Pit Analysis on Inhaul Cable
Etch pit is a common local etch on inhaul cable. Etch pit on the surface of steel wire can produce pits and lead to the appearance of stress concentration due to geometrical discontinuity in the pits area on steel wire. After studying various stress concentration analysis techniques, it is concluded P-method is the best method suitable for the stress analysis of corrosive pits. The analysis results show that the Von. Mises stress at the bottom centre of pits and stress concentration factor in the pit first decreases and then increases with the depth increase of the pits, hi the research on steel wire fatigue life, when paying attention to the maximum stress value, it still needs to consider the etch degree on steel wire section. The calculated data lay a certain foundation for the life study of inhaul cable.
