Shock Pulse Method filters out this phase of the collision, as the magnitude of the vibration is structure and material dependent. Measuring Shock Pulse Signals 

Shock Pulse Method is a signal processing technique used to measure metal impact and rolling noise such as those found in rolling element bearings and gears. Much more refined than other high frequency measurements, Shock Pulse is widely used throughout the world as a basis for predictive maintenance. Rolling element bearings are the most common

The shock pulse transducer is designed to respond in a clearly defined manner when exposed to shock pulses. Because shock pulses contain a broad range of frequencies, they will also contain 32 KHz components that will trigger the transducer to oscillate. The behavior when exposed to a shock pulse is well defined.

3. SHOCK PULSES. Two types of shock pulses, a half-sine shock pulse and a sawtooth shock pulse, are specified. The pulse shape and tolerances are shown on figures 213-1 and 213-2, respectively. For single degree of freedom systems, a sawtooth shock pulse can be assumed to hav e a damage potential at least as great as that of the

The purpose with this description is to give an understanding of what shock pulses are, how they are measured and quantified and finally how to interpret them.

pulse method is selected as the analyses tool to measure the mechanical shock. Shock pulse monitoring does not focus on the vibration phases but.

Interference from other pulse sources;. The shock pulse method can be illustrated by the example of a metal ball fall on a metal object.

I have attached a description that is short and pretty good part from the things around SPM, it is named Shock Pulse Method, it is not invented by SKF but they had a cooperation in the 1970's and later split up otherwise it looks pretty clear but maybe a few more methods exist.
