Describes the different techniques of different applications, including studies of individual machines dynamic phenomena signal enhancement techniques and analysis methods. Many of these techniques can also be applied to other methods of the type of machine, including reciprocating machines. This section provides the format of the draw for the evaluation and diagnosis of machine condition generic parameters. When analyzing vibration signals, this section is divided into two basic methods: time domain method and frequency domain method. This section also contains a number of ways by changing the operating conditions of the refined diagnosis. This section includes only the vibration for machine condition monitoring, most common technical analysis and diagnostics. Many other techniques used in vibration analysis and diagnosis of deep studies to determine the status of the machine, these techniques are beyond the normal continuous monitoring of machine condition range. Detailed description of these techniques is beyond the scope of this section. But these more advanced technologies for specific purposes in Chapter 5 as supplemental information listed. For a particular machine type and size. GB/T 11348 and GB/T 6075 series of standards for the application of broadband vibration amplitude condition monitoring provides a guide. Other documents, such as VDI 3839 and VDI 3841, provides additional information on the specific issue of the machine can detect when the guidance vibration diagnosis. | GB/T 19873.2-2009: Condition monitoring and diagnostics of machines -- Vibration condition monitoring -- Part 2: Processing, analysis and presentation of vibration data

Introduction
This section covers machine vibration condition monitoring in the field, its purpose is to give a dynamic performance monitoring of the machine, to be installed on selected locations
Methods and procedures recommended by the vibration sensor to obtain a signal and data processing and analysis.
Broadband vibration measurements provide an overview of machine vibration intensity, when the machine is abnormally can be observed and alert the user to use the machine.
Way further processing and analysis of vibration signals in accordance with the procedures specified in this part, to provide users diagnose machine problems in one or more reasons
Diameter, it can be used in a more focused continuous condition monitoring.
Listed.
For a specific machine type and size, GB/T 11348 and GB/T 6075 series of standards for the application of the state of broadband vibration amplitude
Monitoring provides guidance. Other documents, such as VDI3839 and VDI3841, provided that can be detected with about guiding the vibration diagnosis
Additional information about the machine body problem.

3.1 General
All measurements are generating a vibration and vibration acceleration, velocity and displacement by measuring the instantaneous value of the sensor is proportional to an analog
The resulting electrical signal. This signal can be recorded on a dynamic analyzer for later analysis or display, for example, displayed on an oscilloscope. in order to
Get the actual vibration amplitude of the output voltage multiplied by a calibration coefficient, which consists of an amplifier and recorder as well as the sensitivity of the sensor must gain
set. Most vibration analysis in the frequency domain, but there are some useful tools include vibration time history.
Figure 1 shows the relationship between the time domain and frequency domain vibration signal. In the figure, combined into four overlapping signal analyzer display
It is displayed in the composite track (black trace). Fourier treatment, analyzers this synthesized signal into four discrete frequencies
Components.
Figure 2 is a complex track on the analyzer screen to see a single sensor signal is relatively simple example. In this example,
Only three overlapping signals, shown in Figure 3, in which separate frequencies are shown in Figure 4.
