| 中文摘要: |
| 首先基于无人直升机尾桨毂轴颈轴套组件的结构形式，介绍了现代无人直升机尾桨毂轴颈轴套组件在疲劳试验中受力形式及承载特点。随后逐一介绍了尾桨叶假件和轴颈轴套组件的载荷标定与计算方法，并同步介绍了试验加载方案及载荷调试原理。最后，将尾桨叶假件上测量剖面应变结合最小二乘法插值调试尾桨叶对接面挥舞和摆振弯矩，同时直接载荷测量调试轴颈监控剖面的挥舞弯矩和摆振弯矩，并将2种载荷调试结果进行了对比分析，确定了合理可行且适用于试验的载荷调试方法，为无人直升机尾桨毂轴颈轴套组件在地面试验中准确承载、传载及结构疲劳寿命评估等提供了可靠的试验技术支撑，同时也为今后类似结构的直升机尾桨毂动部件地面疲劳试验技术发展提供了的参考和借鉴。 |

| Firstly, based on the special framework of tail rotor hub journal and sleeves modules of unmanned helicopters, the loading character and form were introduced. Then, the docking surface load of tail blades and surface measurement load of tail rotor hub journal and sleeves modules were calculated and analyzed, and the fatigue test loading design method and the principle of debugging were presented separately. Finally, by combining the numerical interpolation formula with measuring loads of tail blade fake parts, the docking surface load of tail blades were calculated, and the monitoring profile load of tail rotor hub journal and sleeves modules were also directly measured. After that the above results were compared and analyzed, thereby the reasonable debugging method for this test was confirmed, which can not only guarantee the test running smoothly and loading reasonably in the fatigue test, but also providevaluable reference for the development of tail rotor hub journal and sleeves module fatigue test technology about unmanned helicopters in future. |
