Two kinds of approach.The former is that the vibration isolator being made of spring and damper is installed between the equipment and ground by exciting force, with drop
The transport of low power makes to pass to the exciting force on ground and reduces to the greatest extent, the latter be between the ground and equipment of vibration installation every
Shake device, to reduce motion transmissibility, reduces the response that equipment is generated because ground moves；The response that reduction is swashed equipment can be tried
Make the intrinsic frequency of equipment far from excited frequency in order to avoid cause the resonance of very big response, or increases the damping for being swashed equipment；Increase
The method of damping has: the equipment metal material big using interior friction is swashed, such as cast iron, mg-si master alloy；Using the knot for having dry friction
Structure, such as riveting, spiro connection structure；Using the big composite damping structure being made of metal and viscoelastic material, this structure can be very
Keep damped coefficient constant in wide frequency range, so the multistage formant that broadband random force can be inhibited to eject simultaneously,
The various structures for photographing high-rise metal building from tennis have been widely used in, can also be used as kind of post means for because setting
It counts in machinery equipment that is inconsiderate and generating vibration after operation.
