Abstract
For the fatigue crack generated from the tube-truss crane, the paper determines the crack position and cau-ses with the actual force analysis, classifies and evaluates the cracks.By analyzing the relationship between the crack, re-sidual strength, and fatigue characteristic, the crack-strength-fatigue characteristic curve is drawn for the structural member of tube-truss crane to provide the measures to repair and reinforce existing cracks, and plot the curve of residual strength af-ter repair and reinforcement.关键词
