Don't push presses upper layer elastic device and lower layer's elastic device, provides restoring force, the sliding side of this linear, the restoring force provided
It is linear relationship with sliding distance.When sliding block is moved to outside straightway from inside straightway, structure switchs to non-linear, rigidity
It can increase.The angle that each straightway in side is slided on variation rigidity is directly related with the rigidity of structure, and specific angle needs to combine
Concrete engineering is practical to be determined.Maximum sliding on variation rigidity when total length and the earthquake of sliding side and variation rigidity lower slider side
Distance dependent, maximum sliding distance are limited by the space layout of sliding support, and are slided with variation rigidity upper slide and variation rigidity
The size of plate is related, according to maximum sliding distance, sets the length that side and variation rigidity lower slider side are slided on variation rigidity.
The shock isolation method of the variation rigidity Cultural relics in museum shock isolating pedestal of the utility model, includes the following steps：
1) the two stage respective frequency of variation rigidity historical relic shock isolating pedestal is determined according to the old condition of practical exhibition and historical relic quality
And sliding distance, the quality of each layer structure in variation rigidity historical relic shock isolating pedestal is determined according to the material category of selection and supporting stand size
And rigidity, and then the rigidity and quantity of upper layer elastic device and lower layer's elastic device are calculated, and combine concrete engineering practical
It is specific to determine the angle that side and each straightway in variation rigidity lower slider side are slided on variation rigidity；
2) variation rigidity historical relic shock isolating pedestal is prepared according to calculated result processing, in-site installation is carried out after the completion, in Zhan Chenxian
, the lower fixed slab of variation rigidity historical relic shock isolating pedestal is fixedly connected with the exhibition booth of lower part, and the top surface of variation rigidity upper slide, which is placed, to be fixed
Panel, historical relic are placed in panel；
3) in the case where normally opening up old state, upper roller and bottom roller are located on variation rigidity and slide side and variation rigidity downslide
At dynamic center side, upper layer elastic device is fixed in the upper layer hole of variation rigidity middle slide plate, and lower layer's elastic device fixes under
In the hole of solid plate, by detaining between variation rigidity upper slide and variation rigidity middle slide plate and between variation rigidity middle slide plate and lower fixed slab
Part blocks, and relative displacement cannot occur, and holder top historical relic or panel are in normal operating conditions；
When earthquake occurs, under the geological process of some strength, fastener is destroyed, variation rigidity upper slide and variation rigidity middle slide plate
It is slided along the y axis with X-direction respectively, drives top shoe and sliding block respectively along sliding side and variation rigidity on variation rigidity
While the movement of lower slider side, top shoe and mobile sliding block, upper layer elastic device and lower layer's elastic device are squeezed respectively；On
The compressive deformation of layer elastic device and lower layer's elastic device starts to restore after reaching a certain level, and provides restoring force, makes to become respectively
Rigidity upper slide and variation rigidity middle slide plate reset, so that the kinetic energy that earthquake generates constantly is converted to potential energy, reduce top text
The seismic force that object is subject to.Also, due to the symmetrical broken line form for using two connections, the variation rigidity of structure is realized,
Meet the different requirements under varying strength geological process；Meanwhile in slipping, upper linear bearing sliding rail and lower straight line
Frictional resistance on bearing sliding rail consumes a part of seismic energy again, so that the stress of system is more reasonable.Pass through variation rigidity text
Object shock isolating pedestal extends the period of support and top historical relic compositional system, has achieved the purpose that shock insulation, protects entire historical relic
The safety of system.The advantages of the utility model：
