3 Terms and definitions
The following terms and definitions defined in GB/T 2298 apply to this document.
3.1
Compound damping
The damping state of the combination of two different types of damping in the same vibration isolation and anti-impact component.
3.2
Resonancepeak-free
An elastic system composed of a vibration isolator with a predetermined nonlinear damping and a rigid load, the transmission rate of the system is not large under the specified vibration level
The phenomenon of 1.5.
3.3
Frequencyonlyjustoutoflock-in
The frequency at which the non-resonant peak vibration isolation system changes from a locked rigid state to an elastic state under a certain vibration magnitude.
3.4
Vibration transmissivity
When a vibration system is excited, the ratio of the output (force, displacement, velocity or acceleration) of the system to the input of the same dimension.
