直升机旋翼状态监测和故障诊断试验研究

EXPERIMENTAL STUDIES ON HEALTH MONITORING AND FAULT DETECTING OF HELICOPTER ROTOR

直升机旋翼系统故障诊断在直升机故障诊断中占有很重要的地位。本文采用试验方法及BP神经网络完成了旋翼故障识别和程度识别,为我国直升机旋翼诊断和神经网络在直升机故障诊断中的应用打下一定基础。

The fault diagnosis of a helicopter rotor is of great importance to that of the helicopter. In -this paper, the detection and identification of rotor faults are implemented by BP network with one hidden layer, based on measured data for training and testing the networks. This research can lay the foundation for the fault diagnosis of a helicopter rotor and the application of network to the detection damage in the helicopter.
