To find effective aseismic measures for museum cultural relics

the development and application of isolation devices for cultural relics based on passive control techniques were studied using classification method.Different types of isolation devices from overseas were discussed

their isolation mechanisms as well as isolation results were analysed and helpful advices were proposed.Results show that development and application of passive isolation devices for museum cultural relics in foreign countries are more widely than those at home.On one hand

different types of level vibration isolation devices such as rolling roller

rolling wheel

rolling ball

sliding block

SMA（Shape Memory Alloy）

magnet stone

constant-load spring

laminated rubber and so on have appeared.On the other hand

vertical vibration isolation devices based on parallel links

negative stiffness setups

constant-load springs

air springs

linear guiders

torsion springs and so on have been developed.By rational selection and utilization

these devices can achieve well performance.Besides

the development of new technology makes the application of smaller and higher efficiency isolation devices for museum cultural relics possible.
