飞机起落架动力学仿真技术研究

摘要

Base on a reasonable simplification to the articulated landing gear of a type aircraft, it builds the finite element model and carries out the dynamic analysis by using Abaqus, through which it acquires the interaction force between the tire and the ground. The comparison between the test measurements and computation results has a good agreement and demonstrates that the research method is correct and the computed model is also reasonable.%在对某型飞机摇臂式起落架进行合理简化后，应用有限元软件Abaqus对其进行了有限元模型建模和动力学仿真分析，得到了轮胎与地面间的相互作用力。仿真分析结果与试验结果吻合得很好，表明研究方法正确，计算模型合理。
