The vibration identification of military vehicle seat based on wavelet-scale energy coefficients

The military vehicles seat vibration is one of the main factors affecting the efficiency of crew. In this paper, the wavelet transfrom is used to analyse the military vehicle seat vibration, the vibration energy distribution in different frequency bands is examined by wavelet energy spectrum. The vibration sources of the seat are recognized,!!nd the vibration characters can be identified by the wavelet-scale energy coefficients.
