The device that shakes exports force test device.
Background technology
With the development of modern industry, the requirement of shelter and vibration control level requirement of mechanical equipment especially precision equipment
Also higher and higher, vibration isolator plays the role of noise-and-vibration-reduction by a large amount of use in mechanical equipment.Especially military boats and ships,
The vibration of dynamic property equipment will produce radiation noise of ship, greatly influence the Sound stealth on naval vessel, increase found by enemy and
The possibility of attack.Therefore, the vibration of effective control machinery equipment is of great significance to.
Currently, the vibration control technology of mechanical equipment, whether foundation needs outside energy input that can be divided into passive type and master
Dynamic formula two major classes.Passive type vibration control technology need not provide energy by the external world, generally pass through the realization pair of passive vibration isolation element
Mechanical equipment vibration is effectively isolated, or inhibits the vibration of mechanical equipment by passive type dynamic vibration absorber.It is active to shake
Dynamic control technology needs to carry out drive ram from external world's acquisition energy, is realized by actuator and corresponding vibration control algorithm
Effective control to vibration.Passive type vibration isolator is although simple in structure, and reliability is preferable, but its low frequency vibration isolation is ineffective.
If significantly to promote the vibration isolating effect of passive vibration isolation system, the rigidity for reducing vibration isolator as far as possible is needed.But it is too low
