Title Thermo-mechanical coupling strength analysis of ear- plate-thickened plate hook beam on metallurgical crane
Abstract
Research background and current status of plate hook beam on metallurgical crane are introduced in this paper. Besides, three-dimensional contact problem, finite element contact analysis method and thermo-mechanical coupling problem are also referred here. The application of Pro/E, HyperMesh and ANSYS software is briefly mentioned. The whole process of modeling, meshing and finite element analysis are reported in detail in this paper. The results show that the stress maximum of plate hook beam is in the arc connecting area of ear plate with lower wing plate, and the design of thickened ear plate can truly reduce stress concentration and mechanical stress in a certain degree.
