Introduction
For shock and vibration or suffered various types of equipment for accurate measurement requirements of increasingly urgent, so the vibration and shock sensor
Calibration has become particularly important. Calibration of these have been adopted or recommended a number of ways, this part of GB/T 20485 for some parties
Method are described. Chapter 5 describes several methods that absolute calibration of vibration and shock sensor has proven to be
Reliable.
This section contains two types of calibration of vibration and shock sensor used in common, the fact that according to the vibration measurement or impact measurement
Distinguish sensor is unrealistic.
This section is limited to linear motion acceleration, velocity and displacement sensor calibration; for does not involve force, pressure or strain measuring sensor
Is, of course, some of the sensor may be calibrated using a similar method. In addition, this section does not include transfer for measuring rotational vibration
Sensors, because there is less number of such sensors, wire motion sensor hardware and its calibration method in this section relates also different.
This section contains definitions and describes as a basis for the absolute calibration method. In addition, the General also provides an overview describes the transfer of vibration and shock
Various sensor calibration methods, as well as inter alia the sensitivity of the measurement characteristics calibration method. To achieve the accuracy of known calibration must be detailed
Technical requirements and procedures prescribed fine instrument. The above information about the various calibration methods in more detail in GB/T 20485 in the subsequent sections
Introduction.
The sensor itself can be used as a calibration unit, which may include connecting cables and/or an adapter device. The calibration system must
Always be clearly stated.
This section includes a reference bibliography, references cited in the text in square brackets when the digital representation.

Vibration and shock sensor calibration method
Part 1. Basic Concepts
1 Scope
This section GB/T 20485 specifies the calibration of vibration and shock sensor, comprising measuring sensitivity and other characteristics
method.
This section is recommended for an absolute calibration method using the method as a priority, but also introduces the comparative calibration of vibration and shock pick
(See 5.3), a more detailed description see GB/T 13823 and GB/T 20485 relevant standards.
This section applies to the calibration of linear motion acceleration, velocity and displacement sensors continuously read out, and suggests methods of precedence,
This approach has been shown to give reliable and reproducible results.
This part is not used to calibrate the rotary sensor.

3 Terms and Definitions
ISO 2041.1990 and established the following terms and definitions apply to this section.
3.1
The measured mechanical movement (eg a given direction of acceleration), can be easily converted into the amount of measured or recorded means.
Note. The sensor may include auxiliary equipment, such as Conditioning, the necessary power supply, the necessary electronic components, output indicator or recorder or the like.
3.1.1
Sensor within the specified tolerance limits can be considered as frequency and amplitude of the linear range of the sensor.
3.1.2
Bidirectional electromechanical sensors. Than the force of the current sensor of this type is applied to its generation (in this case the sensor is constrained so that speed is zero)
Equal to its speed and its applied voltage generated by the ratio (in this case the sensor is in an open state, so that current is zero).
For example. magnetic and piezoelectric sensors.
3.1.3
Strain gages as the sensing element of the sensor, the sensor is applied to such incentives do not produce significant mechanical response.
