Numerical Simulation and Analysis of Bearing Capacity of U Beam Steel Arch

摘要

U beam steel arch has widely been used in nonferrous metal mines support especially in deep mining due to its ductile and high bearing capacity. This paper aimed at the simulation analyses based on the finite element method for U beam steel arch production. The comparison of the bearing capacity between the roll bending and die forming were studied. The law was also been analyzed as the forming radius. The results showed that the maximum effective strength of the die forming is the twice of the roll bending. The position of the maximum effective stress of the die forming is at the molded corner, and it appears at the root of the arch of the roll bending. The effective strength increases as the arch radius.
