In this paper, nonlinear finite element analysis about the semi-rigid connected steel frame and top and seat angle with double web angles semi-rigid connection are carried out with ANSYS finite element software. The analysis is a complicated nonlinear problem, which includes plastic development of metal material, geometrical nonlinear caused by large deformation of the structure and contact. Results...
The stresses in rails under wheel loads have a strong bearing on the safety of railway transportation. A prediction of stresses in rails is of interest to both manufacturers and operators. In the past, several models have been developed for the problem. However, due to the complexity of the problem, there is still no ??standard model?? available. The issue addressed in this paper is how to design...
The development of modern transmission design leads to scuffing becoming more serious for transmission gears. The finite element method (FEM) is proposed that can be used as the most economical and effective designing tool for predicting the gears temperature and the distribution, determining whether the tooth scuffing or not, and analyzing the thermal stress and the deformation of gears. The thermal...
