Abstract

Aluminum alloy structural hangers are widely used in subway vehicle. The advantage of aluminum alloy is light weight and corrosion resistance. For different application fields, the structures of aluminum alloy components are very different. They are typically lighter for the same strength and provide better heat conduction. As we know that do FEA (finite element analysis) is necessary before and after the alloy structures have been made. In this paper, a detail analysis was done with FEM (finite element method), and the stress distribution of alloy structural hanger was obtained. Also the FEA results show that the maximum stress is less than the yield stress and the stress concentration of the slot is relatively high.
