The research of load distribution is not only an important part of bearing theory but the basis of studying the other performance indicators of bearings as well. Based on the contact theory of Hertz, the relation of geometric deformation of slewing bearing under certain loads is analyzed, and an analytical formula of load distribution for the slewing bearing under the action of radial force, axial...
Aiming at the design defect of pre-existing Electro-magnetic circuit parameters on Electro-magnetic treatment equipment, the article gives some design methods-field-circuit methods which design and adjust the electromagnetic processing parameters. Mean while, the interdependent relationship of the Electro-magnetic parameters, temperature field parameters and stress parameters is displayed in the models...
Aimed at structure retrofit of sprocket shaft, combining with the practical working conditions, theoretical calculation, finite element method (FEM) Analysis and model test are applied in research. The results show, numerical value of traditional mechanical algorithm is relative small, FEM can express the influence of actual structure, and results are more reliable. FEM Analysis represents stress...
Tunnel excavation design is an important content in the civil engineering, many researches are done based on the linear failure criterions by the analytical solution and numerical solution, but seldom researches are done to apply the nonlinear failure criterion in describing the surrounding rock mass after tunnel excavation, although nonlinear failure criterion shows great advantages over the linear...
According to the Pro/Mechanica analysis platform, by the finite element analysis method, the actual mold honeycomb molded forces, boundary conditions and imposed load in the view of the molded honeycomb mold for the actual operating conditions leading to die due to stress concentration fatigue failure, the reliability of the problem of insufficient. Through the analysis to determine the maximum stress...
