Strength Analysis of Elastic Bar Based on ANSYS Simulation


Article Preview

This paper presents a simulation analysis of stress and strain of an underground rail elastic bar using the commercial finite-element simulator ANSYS-10. Under constant compression displacement of 10.4 mm or the fixed-plug-in displacement of 84 mm, the stress distributions are examined by varying the boundary condition of the corresponding fixed-plug-in displacement or the compression displacement. Results show that the maximum stress which is 1,490 Mpa occurs as the compression displacement is 10.4 mm while the fixed-plug-in displacement is 84 mm. In addition, in both group of scenarios the maximum stress is at the end of the arc of the elastic bar and exceeds the strength limit of 60Si2Mn. While both the compression displacement and the fixed-plug-in displacement affect the stress distribution and the maximum stress, it appears that the effect due to compression displacement is much more significant.
