what is shock pulse monitoring

2022/08/26 · Shock pulses are defined in the test standard and are classified as either a classical shock pulse or a transient representation of a recorded real-world event. Although most classical shock pulses are defined in terms of acceleration, the main purpose of a shock test is to generate a delta-velocity and then inspect the effects of the delta-velocity on the product.

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

What is the Shock Pulse Method? Due to the sensitivity of the Shock Pulse Method, bearing lubrication condition is measurable through the signal monitored as dBc. The dBc is measured in the time wave signal of the shock pulse transducer. The filtered transducer signal reflects the pressure variation in the rolling interface of the bearing.

2003/11/02 · SPM stands for shock pulse monitoring. The term “shock pulse” describes what is produced when a ridge or asperity from one surface contacts a ridge or asperity of another surface when the lubricant film, designed to separate those surfaces, is lost. The pulse is a high-frequency signal that is collected with a sensor tuned to measure noise

The SPM meter measures the shock pulses per second and then lowers its threshold so that two amplitude levels are discovered, first the decibel carpet value 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.

The Shock Pulse Method (SPM) is the front line technique the Hallsta paper mill chose to quickly manage input from its 800 rolls, with 4000 machines and 1 6,000 measurement points. With 8 inspectors, they need a quick method to know whether bearings need to be greased or not, or that damage is present and needs to be monitored more frequently.

Methods and signal forms in vibration & shock pulse analysis. The best bearing ultrasound detector. SPM HD: the best way to detect bearing and gearboxes failures, even at very very low speed.. FFT analysis: often used for identifying the most common machine faults, such as misalignment or unbalance.. Order analysis: Variant of FFT analysis used for machines with variable RPM; instead of the

Shock pulse measurement primarily serves the purpose of preventive maintenance of rolling element bearings. Regular measurements are used to monitor the installation, operating conditions (lubrication, loads, etc.) and the development of the lifetime expectancy (wear rate) of the bearings. These aim at making the best possible use of

Pulse pressure is the difference between the upper and lower numbers of your blood pressure. Pulse pressure tends to increase as you get older, and this number can also be an indicator of health problems before you develop symptoms. If you want to monitor your blood pressure on your own, blood pressure cuffs are available in most pharmacies

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.

These mechanical shocks are elastic waves that mirror the impact-contact-force's time function and the Shock pulse monitoring accelerometer, which is tuned to 

In bearing condition monitoring, management systems not only monitor bear vibration date, but also bear pulse data by a shock pulse method (SPM) [2]. In these cases, the observation indicators are
