• Loose parts
• Mass estimation
• Wavelet energy spectrum (WES)

It is a very difficult problem to realize the mass estimation of loose parts in the mechanical equipment. The result of mass estimation will influence the fault diagnosing of equipment, especially in the loose part monitoring system of nuclear power station which can provide important guidance for the type classification of loose parts. This paper is based on experiments, by wavelet energy spectrum method to make estimation for different impact mass, and by using linear interpolation method to establish the scale peak function. The results show that the method has characteristics of small estimation errors and good consistency, strong anti-interference capacity, and it has better actual application value.
