摘要:

当前对飞机起落架低频刹车耦合振动问题的研究主要停留在考虑轮胎参数影响的起落架纵向单自由度振动特性分析，对于多自由度低频刹车耦合振动的特性研究还有所欠缺。本文基于Simcenter 3D 动力学分析软件建立双轮支柱式起落架刚柔耦合整机滑跑刹车分析模型，研究轮胎竖向刚度和侧偏刚度对双轮支柱式起落架低频刹车纵向、横向和扭转的多自由度耦合振动的影响。结果表明：轮胎的竖向刚度对起落架横向和扭转方向上的振动影响较大，轮胎竖向刚度变化33%，横向和扭转方向上的振动变化5% 左右，轮胎的侧偏刚度对起落架低频刹车横向上的振动影响较大，轮胎侧偏刚度变化33%，横向上的振动变化15% 左右。

Abstract:

Currently, the research on low-frequency braking coupling vibration of aircraft landing gear mainly is relatively lacking. In this paper a taxiing and braking analysis model for rigid-flexible coupling of two-wheel strut landing gear is established in the Simcenter 3D dynamics analysis software. The research results show that the vertical stiffness of the tire has a great influence on the vibration of the landing gear in the lateral and torsional. The vertical stiffness of the tire changes by 33% and the vibration in the lateral and torsional changes by about 5%. The cornering stiffness of the tire has a great influence on the vibration of the landing gear in the lateral. The cornering stiffness of the tire changes by 33% and the vibration in the lateral changes by about 15%.
