TRANSFER PATH ANALYSIS OF RANDOM VIBRATION LOADS
P. LI, Aircraft Strength Research Institute, China
The traditional TPA analysis method is widely used in NVH field, but mainly used for periodic loads. The theoretical research shows that the TPA analysis of random vibration signals can also be carried out in the form of power spectral density(PSD), and the contribution of each transfer path can be obtained.
