| 摘 要： | 摩托车脚踏座在出厂检测时发生断裂。采用断口分析方法对摩托车脚踏座的断裂原因进行了分析，结果表明，零件是经铸造后挤压加工而成，内部残余缩孔的存在以及断口附近有魏氏组织和带状组织，是造成摩托车脚踏座断裂的主要原因．其为脆性解理断裂。

| Abstract: | The breaking of foot-pedal in motorcycle was investigated by macroscopical and microscopical methods. The results showed that the existence of residual hole and the appearance of non-normal structure caused by manufacture process were the main cause. The brittle cleavage fracture of foot-pedal happened due to the stress concentration and the defect in the material. |
