Introduction
Various passive isolators are used to reduce the transmission of vibrations, such as the suspension of automobile engines, the elastic support of buildings, the marine equipment
Flexible support and flexible shaft couplings, and small vibration isolators in household appliances.
This section specifies the driving line method of low frequency dynamic stiffness function of the elastic support member measuring line. This section also includes non-linear static preload
Load-displacement elastic support as long as such elements exhibit a nearly linear vibrational behavior for a given static pre-load. This section is
Flexible element vibration - acoustic characteristics of laboratory measurement methods, one of the series of standards, this series of standards also include the principle of measurement and elastic support dynamic stiffness
The direct method, the indirect method and the driving point method part, ISO 10846-1 provides a comprehensive guide to select the appropriate standard.
The laboratory conditions described in this section include the rational use of static preload.
The result of the driving point method is very useful for elastic supports for preventing low-frequency vibration problems and for attenuating the low-frequency structure sound of the acoustic frequency band.
However, this method does not provide the full character of the vibration isolator used to attenuate low-frequency vibration or shock displacement, for which additional information is required.

Driving Point Measurement Method of Dynamic Stiffness
1 Scope
This section GB/T 22159 describes in detail under a specific pre-load conditions, the elastic support low-frequency dynamic stiffness drive point
Measurement methods. In the elastic support output block, through the input of the force and vibration measurement of the experimental method of stiffness, known as the drive
Point measurement.
The stiffness obtained by measuring the displacement (speed, acceleration) and force of the input is called the driving jogging stiffness. Only in the low frequency range due to flooding
The dynamic stiffness of moving point is equal to the moving stiffness of transmitting moving point. This method can be used to measure the dynamic stiffness of elastic supporting part.
Note 1. GB/T 22159.2 already includes the direct method of dynamic stiffness measurement. The direct method includes the measurement of low frequency dynamic stiffness and in principle has a ratio drive point method
Wider frequency range. However, the driving point method is also included in the series of standards. It is used as a driving point stiffness measurement device (usually very expensive
) Owners are a useful option for extending the use of these devices for the determination of low frequency dynamic stiffness.
This method is suitable for measuring pieces with parallel connecting surfaces (see Figure 1).
Elastic elements used as measuring objects in this section are used to reduce.
a) Vibration of the lower frequency range (usually 20Hz ~.200Hz) to the structure. The structure can radiate undesirable
Fluid sounds (such as air, water, or other sounds);
b) The spread of low frequency (1Hz ~ 80Hz) vibration, if such vibration is too strong, no matter acting on the human body or any size structure
Cause harm.
Note 2. In actual cases, very small or very large elastic supports can not be measured due to the size of the measuring device.
Note 3. This method also includes a sample of continuous supports for slats and shims. This part of the user is responsible for the complex system of these samples vibration - acoustic transmission characteristics
Give a full description.
This section also covers the connection with the test piece parallel and vertical displacement measurement method. The frequency range to which this measurement method applies
Range is f1 = 1Hz to the upper limit of frequency fUL, the usual range of values. 50Hz ≤ fUL ≤.200Hz.
The measurement data obtained by this method can be used.
