This section is equivalent translation ISO /T S10811-2.2000.
For ease of use, this section was modified following editorial.
--- With "this Part" instead of "ISO /T S10811-2";
--- Remove the ISO /T S10811-2.2000 foreword, preface rewritten this section;
--- With a decimal point as a decimal symbol instead of ",". ",";
--- Of ISO /T S10811-2.2000 references other international standards, have been adopted as the equivalent of a standard, instead of using our standard
Corresponding to international standards, is not tantamount to the adoption of a standard for the direct reference to international standards.

Introduction
This section provides a brief description of the three values of the spectral measurement data simplified method for classifying a measure used, the basic idea of its classification
I want to make measurements and concise constant displacement/constant speed/constant acceleration spectral match. Concise description of the spectrum consists of three values. a speed average
Two corner frequency and rms values.

Part 2. Classification
1 Scope
One way to define this part of GB/T 23717, this method GB/T 23717.1 measured data based on the effects on buildings.
Vibration and Shock classification. Hierarchy of environmental vibration conditions as designers, vibration and shock sensitive equipment manufacturers
Building developers and users and usage guidelines.
Vibration and Shock type considered include transfer from the floor, table, wall, ceiling or isolated systems to the role of the device components, which are
It may be produced by the following aspects.
a) external vibration source, such as transport (road, rail or air) or the construction of buildings and construction activities (blasting, piling and vibration close
Real), but also the weather causes vibration and sound of the roar and vibration response due to acoustic excitation;
b) equipment for indoor use, such as presses, forging hammers, rotating equipment (air compressors, air conditioning systems, etc.) and transport within the building or
Operating heavy equipment;
c) Activities related to personnel and maintenance and operation of the device, such as people walking around, especially in the paving on the floor.
The frequency range of interest is typically 2Hz ~ 200Hz. General characteristic frequency less than 100Hz, because it is the performance of the building
The response of various elements thereof.
This section only from the perspective to deal with the largest amplitude of vibration. Other quantitative concept does not involve vibrations (such as fatigue life estimation).

IEC 61260 electrical acoustic octave band and fractional-octave bandwidth filter
3 types of vibration waves
The shock wave can have an impact on the type of precision instruments within the building may be in any form. sine wave, random wave or transient waves. because
Here, the vibration measurement and analysis should be effective against all of the above three types of motion. For a typical vibration source can be an example of a different type wave
as follows.
Sinusoidal vibration a) of rotating machines;
A large number of vehicles on the random vibration b) road;
c) a single transport, piling, impact and explosion of transient vibration.
Frequency of vibration not only determined by the vibration source, but also by the dynamic characteristics of the building. Measurement and analysis methods described in this section
It can be used with any type of vibration waveform.
