Quantitative detection approach for transmission system of helicopter based on physical model and gray relational analysis

  • 摘要: 结合物理模型与灰色理论,提出了一种直升机传动系统损伤定量检测方法.针对直升机主传动系统的2K-H行星轮系,建立了太阳轮缺齿损伤的物理基模型,通过仿真获得了不同损伤严重度的行星轮系振动信号.选择并计算仿真信号的特征向量,并以此作为损伤特征的标准模式,然后对待检信号特征向量与标准模式进行灰色关联度分析,根据关联度对损伤进行定量检测.试验数据的验证结果证明该方法对行星轮系太阳轮缺齿损伤具有良好的定量检测能力,并可将之应用于其他旋转机械典型损伤的定量检测.
