Harmonic analysis and optimized vibration sensor locations of the helicopter intermediate gearbox

  • 摘要: 研究了多自由度的振动数学模型.通过系统的故障频率来确定振动传感器的安装位置,提出了一种基于故障频率敏感的振动传感器优化布局方法,建立了直升机中减速器机匣有限元模型.利用谐响应分析方法,对中减速器机匣施加一故障激励信号.研究表明:机匣的不同位置对激励信号响应的振动幅值明显不同,齿轮故障时往往在啮合频率及其倍频处形成以转频为间隔的边频带,对该边频响应振幅最大的位置就是振动传感器安装的最佳位置,并提出了振动传感器优化布局函数.此方法同样适用于直升机传动系统其它部件的振动传感器位置选择,也适用于其它旋转机械的振动监测.
