what is shock pulse monitoring

Shock Pulse Monitoring. SPM is an abbreviation for the Shock Pulse Method, which 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

The shock pulse method was invented in the late 1960s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves 

08/24 · Back to: Shock Testing. The various classical shock pulses have unique purposes. Generally, each of these unipolar pulses excites a wide range of frequencies in a short period of time but in different ways. Classical pulses are primarily defined in acceleration; the shape of the acceleration waveform determines the frequencies and the degree to

Shock pulse method (SPM) is a 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 been further developed and broadened and is a worldwide accepted philosophy for condition monitoring of rolling bearings and machine maintenance.

To measure Shock Pulse we use filtering combined with a special Accelerometer, which is designed with specific characteristics for Shock Pulse Measurements. If 

Shock pulse technology is generally well known to vibration analysts and reliability technicians. A handheld combination of sensor and display meter would 

03/24 · Your machines contain rotating rolling bearings that create shock pulses during operation. These pulses indicate the condition of your machine. By using Shock Pulse Monitoring (SPM), we measure and trend this data. Ultimately, this makes it possible to predict machine failures and avoid breakdowns. NOTE: Your machines are not equipped with SPM

Step 1 - Amplification. Shock Pulse signals are relatively small in amplitude and do not travel great distances. To amplify the small Shock Pulse signal the piezo electric crystal stacks, which are the actual element in an. accelerometer that generates signals, are constructed in such a fashion that they are excited by the 36 kilohertz.

The LR/HR method was developed from the original Shock Pulse Method for condition diagnosis of rolling element bearings. It allows the precision analysis of

SPM HD can be used to monitor applications in the 0.1 - 20 000 RPM range. Throughout their lifetime, bearings generate shocks in the interface between the loaded rolling element and the raceway. These shocks 'ring' the shock pulse transducer, which outputs electric pulses proportional to the shock magnitude.

Shock pulse transducers can be used in permanent SPM installations for bearing monitoring. They are installed in countersunk mounting holes on the bearing housings. A shock pulse transducer converts the shock pulses emitted by the bearing into electric signals.

08/22 · The shock pulse method was invented in the late 1960s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves, or shock pulses, or

Vibration analysis is done to analyze the realiability and health of the machines and their components by looking for anomalies and monitoring change from the vibration signature of a system. The vibration of any object in motion is characterized by variations of amplitude, intensity, and frequency. These vibration signatures can be correlated to physical phenomena, making it possible to use

The form of the shock pulse and particularly the pulse duration are equally important. For example, a short 1 ms 300 g shock has little damage potential and is not usually of interest but a 20 ms 300 g shock might be critical. Monitoring of goods in transit. Shock loggers can be used to monitor fragile and valuable goods during transit and

Shock pulse amplitude is due to three basic factors: Rolling velocity (bearing size and rpm) Oil film thickness (separation between the metal surfaces in the rolling interface). The oil film depends on lubricant supply and also on alignment and pre-load. The mechanical state of the bearing surfaces (roughness, stress, damage, loose metal particle).
