根据航空发动机振源信号的相互独立性.阐述了利用盲分离技术对航空发动机振动信号进行分离的原理和实现。利用Fast ICA算法对某型涡轮风扇发动机转子产生的振动信号进行了盲分离实践。
The blind source separation was used to recover the vibration signals of independent sources of aeroengine. The theory and separation of the aeroengine's vibration signals is expounded by using blind source separation techniques. It also carried out the separation of the vibration signals that come from rotor of a turbofan engine by Fast ICA algorithm.
