| Abstract: | A type of high strength aluminum alloy profile section with mid-beam was introduced. The simulation result shows that with the premises of maintaining design structure and manufacturing equipment,this type of aluminum alloy profile section can effectively increase the compressive strength of EMU aluminum alloy vehicle body. The research data and simulation test results provide theoretical reference and technical support in designing aluminum vehicle body meeting higher standard of strength and stiffness. |
