| 摘 要： | 针对发动机管路制造偏差和运动位移的补偿要求,对金属软管在航空发动机上的应用进行研究。根据金属软管的系统、结构尺寸、接口参数和位移补偿,采用样条曲线对软管路径进行拟合,并运用有限元求解变形后的路径形状的计算方法对金属软管的长度和补偿工作条件下的曲率半径进行了分析。结果表明:金属软管的管形变化可满足发动机位移补偿要求,并为金属软管在某型发动机上的应用提供依据。

| Abstract: | To meet the compensation requirements for pipe manufacturing deviations and movement displacement of the engine, the application of the metal hose for aeroengine was investigated. According to metal hose of system, structure size, interface parameter and displacement compensation requirements, the hose path was fitted by spline curve. The length of metal hose and curvature radius at compensation work conditions were analyzed by the path shape calculation method of ANSYS finite element solving deformation. The results show that the tube style changes of the metal hose can meet displacement compensation requirements of engine and provide reference for application of metal hose for an aeroengine. |
