| Port container crane pulley wear failure is one of the difficult problems confusing the engineering industry currently. Because the contact between the pulley and steel wire rope is quite complex and pulley wear process is affected by many factors, the pulley wear mechanism has not been revealed until now.This thesis take the container crane SECT-61T-8113 produced by ZPMC as the study subject, by using theoretical, ADAMS simulation and FEA methods analyzed the wear and contact stresses between pulley and steel wire rope. The obtained results include:By analyzing the moving characteristics of the crane main lifting system, crane's real structural parameters and operation motion parameters, got the pulley's displacement, velocity and acceleration curves, got the steel wire rope's force change curves on the Pulley 1 and 2. By taking dynamic analysis to the pulley and steel wire rope, established a calculating method and analytical model which can be used for calculating the contact stresses between pulley and steel wire rope, obtained the stress distributions and maximum contact stresses on the pulley groove surface. Based the linear fatigue cumulative damage theory, calculated the pulley's fatigue life span. According to the fatigue wear theory and the steel wire rope cutting mechanism, analyzed the causes of pulley wear indentation. By using simulation software ADAMS established the simplified main lifting system virtual prototype model, analyzed the steel wire rope's force values in crane's different operation stages. Found that the obtained results have a good match with the results obtained by theoretical method. By using the software ANSYS calculated the-contact stress distributions on the pulley groove surface and got the maximum forces on the steel wire rope. The simulated results have a good match with the results obtained by theoretical method.The results obtained in this thesis will be helpful for solving the pulley wear problem on the crane SECT-61T-8113. |
