【摘要】为使某MPV牵引装置强度满足设计目标，保障牵引装置在极限工况下不发生断裂失效，通过ABAQUS隐式分析对牵引装置进行不同工况下的强度分析和改进设计分析，试验验证结果表明，增加料厚对牵引装置强度改善明显，但需要配合采用翻边、打孔、增加加强筋等结构特征优化方法。

【Abstract】In order to make the strength of an MPV traction device meet the design objective and ensure that the traction device does not fracture and fail under extreme working conditions， ABAQUS implicit analysis was used to conduct strength analysis and improved design analysis of the traction device under different working conditions. The test verification results show that increasing the material thickness significantly improves the strength of the traction device. However， it is necessary to adopt the optimization methods of structural features such as flanging， punching and adding reinforcing ribs.
