Vibration analysis and the Shock Pulse Method (SPM) are two of the most popular condition monitoring techniques used in Condition-Based Maintenance (CBM) 

Vibration enveloping is commonplace for many of you. 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 impact signals, are generated. The amplitude of these impacts is determined by three different parameters.

A comparison with vibration enve- loping techniques is made as well. 2 The Shock Pulse Method. 2.1 Shock pulses. Shock pulses are elastic waves propagating in “ 

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. [1]

The SPM HD Shock Pulse Monitoring is a further development of Shock Pulse Method (SPM); which can be used for easy, fast and reliable diagnosis of the 

Since the incorporation of our organization, we are offering Shock Pulse Monitoring System to our clients. This is apt for shock pulse measurement.

In recent decades, the shock pulse method has been developed to detect faults in the early stage of rolling element bearings degradation. In this paper, the 

The shock response spectrum is the peak absolute acceleration response of each SDOF system to the time history base input.3As an alternative, this function can be represented in terms of its peak positive and peak negative responses. The dimensions are peak response (G) versus natural frequency (Hz).

Figure 5 shows the shock response spectrum corresponding to the example in Figure 4. 2 In contrast, the level at a center frequency in a random vibration power spectral density represents the average mean square level across the band. 3 Another shock response spectrum format is based on the relative displacement of the mass. An

We offer advanced vibration monitoring techniques for early detection of a wide variety of mechanical fault conditions such as unbalance, misalignment, resonance, looseness, and faulty gears or bearings on all types of rotating machinery. Machine vibration monitoring is the most widespread method to determine the health of rotating equipment.

The pressure wave quickly dampens out. The pressure wave that first goes through the materials (before it starts to vibrate) is called a “shock pulse”. While 

To measure Shock Pulse we use filtering combined with a special Accelerometer, which is designed with specific characteristics for Shock Pulse Measurements. If designed properly, this same accelerometer can be used to measure normal vibration signals as well. Step 1 -

SPM HD. SPM HD® is a patented further development of the Shock Pulse Method (SPM) used for fast, easy, and reliable diagnosis of the operating condition of rolling element bearings. It provides easy-to-understand condition evaluation in a green-yellow-red scale, as well as crystal-clear spectrums and time signals for further analysis.

Shock Pulse Monitoring A Snapshot. Unless an individual is involved with some form of machinery vibration analysis, the term "Shock Pulse" (Monitoring) is unknown and somewhat foreign. Officially, and accurately, it is a technology relying on the physical principle that sound travels undiminished through metal objects for great distances.

Apr 19,  · Most of the ISO standards for machinery vibration monitoring and analysis are guided by technical committee TC108, Mechanical vibration and shock. TC108 is comprised of 22 Participating (P-member)

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 

The results of this thesis show a distrust towards vibration monitoring, while other means of condition monitoring such as lube oil and thermal analysis is common on board. This distrust can be related to the complexity of the subject of vibration monitoring as well as a lack of training, thus, lack of knowledge.

The combination of vibration and shock pulse measurement is ideal for monitoring mine hoist performance. The shock pulse technology is very suitable for detection of bearing damages in typical industrial environments, while vibration technology is optimal for low frequency-related fault conditions like unbalance, loose gears and misalignment.

Shock and vibration logger with integrated 3-axis digital accelerometer and lithium-polymer battery. A shock data logger or vibration data logger is a measurement instrument that is capable of autonomously recording shocks or vibrations over a defined period of time. Digital data is usually in the form of acceleration and time.
