摘要:
以铝合金轨道交通车辆为研究对象，研究车体的静强度特性，包括：总结铝合金材料应用于轨道交通车辆的优势与不足；分析铝合金车体结构及主要技术参数；建立仿真模型，分析典型工况下的车体静强度；通过仿真获得不同工况下车体应力分布情况；通过试验验证车体关键部位的应力及安全系数；分析铝合金车体静强度特性。仿真和试验结果显示，轨道交通车辆铝合金车体整体安全系数较大，但车门角、车窗角等区域应力集中较明显，因此，设计时应重点考虑轻量化及应力集中区的局部强度问题。
Abstracts:
Taking the aluminum alloy rail vehicle as the research object，the static strength characteristics of the car body are studied. The advantages and disadvantages of aluminum alloy materials applied to rail vehicle are summarized，the structure and main technical parameters of aluminum alloy car-body are analyzed. Then，by establishing a simulation model，the typical working conditions are determined to analyze the static strength of the car-body. The stress distribution of the car-body under different working conditions is obtained through simulation analysis，the stress and safety factors of the car-body key parts are verified by experiments. On this basis， the static strength characteristics of the aluminum alloy car body are analyzed. The simulation and experiment results show that the overall safety factors of the car-body are quite high，and the stress concentrations in the corner areas of the door and window are obvious. Therefore the design should focus on the lightweight and local strength concentration zones.
