摘　　要：本文对火箭弹射座椅传爆机构振动试验中支座断裂失效现象、安装位置和作用进行了简要介绍;对可能造成支座断裂失效的原材料、尺寸、工艺生产过程、试验条件、断口、设计及工况强度等主要因素进行了系统排查、分析和验证,最终找准了零件失效的机理,并准确定位。经有效验证,制订了切实可行的预防、杜绝措施。通过本次失效分析研究,不仅消除了顾客方对于产品使用的顾虑,同时,对提升航空产品机械加工表面完整性质量控制起到积极的警示、指导和借鉴意义。The detonation mechanism bearing vibration test failure phenomena, the installation and role of rocket ejection seat were introduced. The raw materials, size, production process, test conditions, fracture strength, design and operation the main factors of the system that may cause abutment fracture were checked, analyzed and verified. The mechanism of component failure and accurate positioning were identified. The aviation products machining surface integrity quality control, guidance and reference meaning were enhanced.
