Shock Pulse Method
Shock Pulse Method, also known as SPM, is a patented technique for using signals from rotating rolling bearings as the basis for efficient condition monitoring of machines. From the innovation of the method in 1969 it has now been further developed and broadened and is now a worldwide accepted philosophy for condition monitoring of rolling bearings and machine maintenance.
== Difference between shock pulse and vibration ==
Consider a metal ball hitting a metal bar. At the moment of impact, a pressure wave spreads through the material of both bodies (1). The wave is transient (quickly damps out). When the wave front hits the shock pulse transducer, it will cause a dampened oscillation of the transducer's reference mass. The peak amplitude is a function of the impact velocity (v).
During the next phase of the collision, both bodies start to vibrate (2). The frequency of this vibration is a function of the mass and the shape of the colliding bodies.
