Multi-body Dynamics Modeling of Landing Gear Shimmy and Application in Shimmy Flight Test based on Model

  • 摘要: 基于LMS Virtual.Lab Motion平台建立了前起落架摆振刚体动力学模型,并利用落震试验进行初步校核;其次在PATRAN中对起落架关键部件进行柔性化处理,建立前起落架摆振多体动力学模型;然后进行摆振工况仿真,识别出工作模态,并从时域和频域两个角度与飞行试验结果反复对比,不断修改更新模型,完成模型标定;最后用模型扩展试验包线,验证了起落架在整个包线范围内的稳定性。
