| 摘 要： | 在非惯性坐标系中建立了起落架支柱的动力学模型。与飞机地面运行的六自由度模型结合，可以考察非直线滑跑飞机的起落架摆振现象及飞机地面滑行的方向稳定性。以Ｋ８飞机为例，考察了非直线滑跑模型与传统的直线滑跑模型的摆振特点及飞机的滑跑稳定性。算例结果合理，表明模型可供有关研究参考。

| Abstract: | A dynamic model of landing gear struts is introduced in a non-inertial coordinate system. Together with a six degrees of freedom model of aircraft ground handling, the model can be applied to investigate the landing gear shimmy and the directional stability of aircraft undergoing non-straight taxiing. Take the K8 aircraft as an example, motions of the strut under both the straight and non-straight taxiing are simulated as well as the directional adjusting procedure of the airframe. Results of the example are reasonable, indicating that the model may have some value in related research. |
