characteristic:
1. Wide applicability: It can be used for various mechanical
systems and structures, including buildings, bridges, vehicles,
etc.
2. Efficient vibration isolation: It can effectively reduce
vibration transmission and minimize the impact of the system on the
surrounding environment or other components.
3. Adjustable: It can adapt to different vibration frequencies and
amplitudes by adjusting its components, such as the stiffness of
the spring or the damping coefficient of the damper.
4. Durability: It usually has a long service life and can work
continuously and stably.
5. Energy conservation and environmental protection: By dissipating
vibration energy or converting it into other forms, it helps to
save energy and reduce environmental impact.
Application:
1. Building structure vibration isolation: used to prevent
vibration transmission of building structures or bridges under
external excitations such as earthquakes or wind, and reduce damage
to buildings.
2. Mechanical equipment vibration isolation: Used in ships,
aerospace vehicles, automobiles, trains and other transportation
vehicles, as well as factory equipment, to reduce the noise and
damage caused by mechanical equipment vibration.
3. Vibration isolation for electronic devices: used to protect
precision instruments, optical equipment, semiconductor production
equipment, and other equipment that are sensitive to vibration,
ensuring their normal operation.
4. Earthquake disaster prevention engineering: In earthquake prone
areas, installing non resonant peak isolators can reduce the
vibration transmission of building structures and improve their
seismic performance.
5. Aerospace field: Widely used in aerospace equipment such as
spacecraft and satellites to help reduce the impact of vibration on
equipment and loads.
