Result of calculation, actual tests and the engineering experience that present inventor combines finite element analysis are drawn in the present embodiment
The adjustable compounded shock isolating pedestal 100 of rigidity mechanical property rule：
The situation that height of support, 14/ middle steel plate of middle steel plate, 24 number of plies of 10/ slip support abutment 20 of shock isolating pedestal determine
Under, the radius of 14/ middle steel plate 24 of 13/ intermediate rubber layer 23 of intermediate rubber layer and middle steel plate is to horizontal rigidity and vertical
Stiffness effect is smaller.Therefore, the radius of 14/ middle steel plate 24 of 13/ intermediate rubber layer 23 of intermediate rubber layer and middle steel plate can be with
Governing factor as rigidity fine setting；
Height of support, 13/ intermediate rubber layer 23 of intermediate rubber layer and the middle steel plate of 10/ slip support abutment 20 of shock isolating pedestal
In the case that 14/ middle steel plate, 24 radius determines, the number of plies of 14/ middle steel plate 24 of middle steel plate to compound support horizontal rigidity with
Vertical rigidity influence is very big, and 14/ middle steel plate of middle steel plate, 24 number of plies can be as the major consideration of stiffness equivalent；

Exemplified by below using most common staircase in market as equipment W2 to be installed, the adjustable composite shock insulation branch of rigidity is illustrated
The operation principle of seat 100 and its shock insulation application effect in heavy electromechanical equipment.The adjustable compounded shock isolating pedestal 100 of rigidity by
10 two kinds of bearings of one slip support abutment 20 and two shock isolating pedestals are composed, and slip support abutment 20 is centrally located, two shock insulation branch
Seat 10 is symmetrically arranged in the both sides of slip support abutment 20.
Staircase structure is considered when shock insulation consumes energy, it is necessary to consider the rigidity of staircase and building structure connects bearing.The master of staircase
Body structure is the tilting truss of a Pin, from the aspect of structure design, has upper and lower bound to the vertical rigidity of truss support
It is required that.On the one hand, the vertical rigidity of staircase bearing will be enough during the dead weight for bearing structure and electromechanical equipment normal operation
Dynamic load, while ensure customer take staircase when comfort level, therefore electromechanical equipment structural bearings vertically cannot be too soft, erect
Need to design a vertical rigidity lower limit to rigidity；On the other hand, vertical rigidity needs to design a rigidity upper limit, when earthquake comes
Temporarily, geological process distributes to structure by rigidity power, and the vertical rigidity of bearing is too big, and the vertical support of electromechanical equipment structure is anti-
Power is just very big, destruction can be equally produced to electromechanical equipment structure, therefore staircase device structure needs to design connects bearing
Vertical rigidity upper limit value.In horizontal direction, bearing, which needs certain horizontal rigidity, cannot allow passenger to feel staircase operational process
The horizontal movement of middle structure；On the other hand need to allow staircase to have certain deflection yoke in horizontal direction.Lower mask body introduces shock insulation
The setting of bearing 10, slip support abutment 20
(1) shock isolating pedestal is set：
First, the installation space of staircase structure is limited, it is necessary to substantially determine the height of bearing according to staircase structure；Then,
The performance parameter designed according to requirement of the staircase and girder structure to horizontal rigidity as shock isolating pedestal 10, determines middle steel plate 24
The number of plies；The radius of intermediate rubber layer 23 and middle steel plate 24 is finely adjusted, the horizontal rigidity of shock isolating pedestal 10 is met staircase
Limit value requirement of the structure to bearing horizontal rigidity.Reserved rigidity adjustment hole K1 among shock isolating pedestal 10, as rigidity storage device,
For carrying out rigidity fine setting after compound support is eventually formed.
(2) slip support abutment is set
Height and the shock isolating pedestal 10 designed for designing slip support abutment 20 are contour；Consider product manufacturing and the facility of installation
Property, the radius for designing 20 intermediate rubber layer 23 of slip support abutment is consistent with 23 radius of intermediate rubber layer of shock isolating pedestal 10；Sliding branch
The vertical rigidity of seat 20 is equal to the vertical rigidity value that electromechanical equipment truss structure subtracts vertical rigidity limit value shock isolating pedestal 10.It is sliding
Reserved rigidity adjustment hole K1 among bearing 20 is moved, as rigidity storage device, in the feelings that compound support vertical rigidity is short of a little
Under condition, the vertical rigidity of compound support toward the stiffness tuning rod of filling metal material in the K1 of stiffness tuning hole, can be increased.
In conclusion considering the electromechanical equipment of shock design, horizontal rigidity and vertical rigidity to bearing have stringent
Control requires.Meanwhile the installation space of electromechanical equipment structure is limited, height and radius to bearing have stringent limitation, because
This general single independent shock isolating pedestal 10 is extremely difficult to the limit value requirement of its rigidity.Using rigidity provided in an embodiment of the present invention
The adjustable shock isolating pedestal 10 that meets can be good at meeting requirement of the electromechanical equipment shock insulation to the mechanical property of bearing, have extensive
Application prospect.
