| 摘 要： | 为排除某型航空发动机燃油导管在外场使用过程中连续发生的断裂故障,对该导管的装配工艺、工作环境、功能及静频和动应力等进行了详细分析。分析结果表明,导致导管断裂的根本原因是导管设计强度不足和检查要求过低。有针对性地提出了排故措施,使同类故障发生的几率大大降低。

| Abstract: | In order to eliminate the continuous fracture of the fuel pipe for an aeroengine during the field operation,the analysis of the assembling technology,the operating ambient and functions,the static frequency and the dynamic stress of the pipe were conducted in detail.The analysis results show that the lacking design intensity and the low inspecting demands are the basic reasons for the pipe fracture.The measures are proposed pointedly so that the same fracture probability is highly reduced. |
