摘　　要：动静轴结构旋翼轴是一种具有抗弹击能力的新型直升机旋翼轴构型,拟对自主设计的鼓形花键动静轴结构旋翼轴和柔性联轴节动静轴结构旋翼轴进行载荷分离特性研究。利用有限元软件对这2种动静轴结构旋翼轴的载荷分离系数进行仿真分析,并开展多通道加载试验加以验证。结果表明采用7 mm壁厚静轴时动静轴结构旋翼轴的载荷分离系数相比采用4 mm壁厚静轴时明显提高;柔性联轴节动静轴结构旋翼轴的综合载荷分离系数为77.37%,略高于鼓形花键动静轴结构旋翼轴的76.33%。研究结果可为直升机动静轴结构旋翼轴的设计提供指导。Rotor shaft with dynamic and static axis structure is a new type of rotor shaft configuration with anti-ballistic capability for the helicopter. It is planned to study the load separation characteristics of independently designed drum-shaped spline rotor shaft and flexible coupling rotor shaft with dynamic and static axis structure. Through the finite element software, the load separation coefficients of two kinds of rotor shafts with dynamic and static axis structures were simulated, and the verifiable multi-channel loading tests were carried out. The results showed that when the wall thickness of static shaft was 7 mm,the load separation coefficient of rotor shaft with dynamic and static axis structure was significantly higher than that when the wall thickness of static shaft was 4 mm.The comprehensive load separation coefficient of flexible coupling rotor shaft with dynamic and static axis structure was 77.37%, which was slightly higher than that of drum-shaped spline rotor shaft with dynamic and static axis structure. The research results provide guidance for the design of rotor shaft with dynamic and static axis structure in the helicopters.
