The shock pulse method was the start of condition monitoring and condition based maintenance, targeting the machine part that causes most breakdowns, the bearings. The scientific task was to find a physical event that mirrored bearing con- dition, quantify it, and transform the mea- sured value into a condition reading.

later. Shock pulse measuring and evaluation is carried out in less than a minute. Since vibration measuring test methods are uncertain, 

the shock pulse on the system through the use of a single-degree-of-freedom idealization, assuming that the fundamental mode parallel to the direction of the pulse is the sole contributor to maximum deformation and corresponding stresses. This method utilizes a combination of Rigid Formats 3 and 1 in place of Rigid Format 9 or 12.

The enveloping technique used by vibration analysis attempts, by manipulating the signal, to make shocks visible and measurable in the frequency domain, simply 

This Shock Pulse is in the ultrasonic frequency band and typically occurs around a center frequency of 36 kilohertz. The amplitude of the Shock Pulse is relative to the velocity of the

At present, the shock pulse method [5, 6] is quite successfully used to control the strength properties of concrete. The application of the method, however, has its own characteristics, which

The Shock Pulse Method is the monitoring and analyzation of high freauency compression (shock) waves generated by a bearing while rotating. From this.

This method is to detect mechanical shocks caused by faults in rolling bearings. The shock-pulse method has been introduced into industry and some of this

Compared with vibration-based measurements, the acceleration-sensor-based shock pulse method (SPM) has been proven to be more effective, 

Aug 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

Aug 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 impact signals, are generated. The amplitude of these impacts is determined by three different parameters. The first parameter, the mechanical bearing condition, is represented by

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

In simple terms, the Shock Pulse Method detects development of a mechanical shock wave caused by technique. it is possible to measure the shock pulses -.

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.

Dual Action Lithotripsy System The Shockpulse-SE (Stone Eliminator) is the next generation Cyberwand system from Olympus, offering dual action lithotripsy with proprietary technology to simultaneously produce constant ultrasonic wave energy and intermittent shockwave (ballistic/mechanical) energy via a revolutionary single probe design. The ShockPulse offers

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.

where τ – the shock pulse duration, ms; ρ1 and ρ2 – the density of the hammer material and the material under test, respectively, kg/m 3 ; V 0 – relative velocity of bodies at the initial

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 viscosity as well as alignment and pre-load.
