Problems solved by technology

However, since the damping characteristics of viscoelastic materials and disc springs are quite different, and how much the two are related, these are to be determined through experiments; especially, when the three-dimensional vibration isolation system is compressed to During tension transition, although the disc spring does not work, the energy stored in the disc spring will be superimposed on the viscoelastic damper, so that the viscoelastic damper can obtain a larger initial acceleration, while the viscoelastic damper is a A speed-sensitive damper, obviously the impact of the energy stored in the disc spring on the viscoelastic damper cannot be ignored, but how to calculate the impact is a difficult matter
Another example is a three-dimensional shock-isolating device disclosed in a patent application with the publication number CN101761147A. When the device transitions from compression to tension, the energy stored in the six disc springs will also be transmitted to the diamond-shaped steel plate damper through the screw rod. There is also the problem of design and calculation difficulties
In addition, the horizontal limit and tensile mechanism composed of sliders, sliding guide rails and high-strength cables in the scheme of the CN101761147A patent application not only makes the design and calculation difficult, but also increases the complexity of the entire seismic isolation system

Embodiment Construction

[0021] see Figure 1~4 , the three-dimensional seismic isolation support in this example includes an upper connecting plate 1, a lower connecting plate 2 parallel to each other, and four rod-guided disc spring dampers 3 arranged between the upper connecting plate 1 and the lower connecting plate 2 The connecting rod 3-1 at the two ends of each pull-rod-guided disc spring damper 3 and the upper connecting plate 1 and the lower connecting plate 2 are respectively connected together by universal ball joints to form a left and right side symmetrical, front and rear Two laterally symmetrical quadrangular truss structures. The included angle between the rod-guided disc spring damper 3 and the lower connecting plate 2 described in this example is 70°.

[0022] The connecting rod 3-1 at the two ends of the above-mentioned tie rod-guided disc spring damper 3 is the same as the universal ball joint connection structure between the upper connecting plate 1 and the lower connecting plate ...

Abstract

The invention relates to a three-dimensional pull rod guide type belleville spring shock insulation support seat. The support seat comprises an upper connecting plate, a lower connecting plate and four pull rod guide type belleville spring dampers, wherein the upper connecting plate and the lower connecting plate are parallel to each other, the four pull rod guide type belleville spring dampers are arranged between the upper connecting plate and the lower connecting plate, and connecting rods on both ends of each pull rod guide type belleville spring damper are connected with the upper connecting plate and the lower connecting plate respectively by universal ball joints, so that a quadrangular frustum pyramid structure of which every two opposite side surfaces are symmetrical is formed.The three-dimensional pull rod guide type belleville spring shock insulation support seat has the effect of overturning resistance, and real three-dimensional shock insulation can be realized.

Description

technical field [0001] The invention relates to a building anti-vibration (or vibration) device, in particular to a three-dimensional shock-isolation device. Background technique [0002] The three-dimensional seismic isolation device is an anti-seismic isolation device installed between the building and the foundation, which can effectively absorb and dissipate externally input energy from multiple dimensions, so as to achieve the purpose of protecting the safety of the building. Three-dimensional seismic isolation devices are usually composed of vertical and horizontal seismic isolation bearings, which absorb vertical and horizontal seismic waves respectively. [0003] As we all know, the development of three-dimensional seismic isolation devices depends on the technical progress of the damper. At present, there are three main types of mainstream dampers that are actually used in practical applications, namely laminated rubber dampers, metal spring dampers (mainly disc sp...
