In tradition shock insulation, under less horizontal force action, earthquake isolating equipment deforms, and horizontal displacement increases with the increase of power；Preset the shock insulation flexible restoring organ skeleton curve starting load and there is the first rigidity and the second rigidity, first rigidity is determined by elastic buffer sheet 19 rigidity, this rigidity value is big, second rigidity is identical with tradition shock insulation post-yield stiffness, trial curve is shown in Figure 17, and the tables of data corresponding with this trial curve is as shown in table 1.

Presetting the shock insulation flexible restoring organ starting load when horizontal force is less than default startup load, only there is relatively small deformation in elastic buffer sheet 19, and device just starts to deform after more than default startup load.Under identical horizontal force F effect, preset the shock insulation flexible restoring organ starting load and be subjected to displacement as d1, tradition earthquake isolating equipment is subjected to displacement as d2, illustrates when identical isolating affection, and presetting the shock insulation flexible restoring organ deformation more traditional earthquake isolating equipment of d1 starting load, to deform d2 little a lot.

Start control shock insulation apparatus and there is following distinguishing feature:

(1) start control shock insulation apparatus and combine protected object and earthquake each characteristic, with tripping force for control device, it is achieved protected object earthquake protection purpose.Whether protected object topples over relevant with its depth-width ratio and suffered seismic force size, and when seismic force is less, protected object is stable, and this performance all obtains checking in theory analysis and test；When earthquake amplitude is bigger, device just starts work, it is achieved protected object shock insulation is protected；

(2) start control shock insulation apparatus and there is good reset function.

(3) start control shock insulation apparatus under reduced size, action of strong earthquake can be resisted, deform little.Start and control shock insulation apparatus by the precompressed to steel spring, under action of strong earthquake, device also only produces finite deformation, starts control shock insulation apparatus and can be processed into reduced size, can meet installing space and the limited condition of space, and then be greatly improved and start the applicable model controlling shock insulation apparatus.
