| 摘 要： | 为了更好地进行起落架摆振动力学特性研究，有必要开展起落架摆振动力学仿真分析。利用Matlab／Simulink建立某型飞机前起落架摆振问题的动力学模型，进行动力学仿真，给出不同速度和防摆阻尼系数下的扭转角、扭转角速度、侧滑角和侧向位移的时间历程曲线，并将五组不同算例的仿真结果与相关文献的结论进行对比，验证了本文仿真模型的正确性。

| Abstract: | In order to conduct nose landing gear shimmy simulation dynamics research, it is required to start landing gear shimmy dynamic simulation analysis. By using Matlab/Simulink the shimmy dynamics model of one aircraft nose landing gear is built and the dynamics simulation is conducted. The time history curves of yaw angle, yaw rate, torsional angle and lateral displacement are given. The results between five different examples and the conclusion of related literature are compared. The correctness of our simulation model is verified. |
