Low-frequency high-bearing-capacity three-dimensional vibration isolation or shock isolation shock resistance support

Abstract

The invention provides a low-frequency high-bearing-capacity three-dimensional vibration isolation or shock isolation shock resistance support. The support adopts a vertical-upper-portion and horizontal-lower-portion or horizontal-upper-portion and vertical-lower-portion vibration isolation or shock isolation structural form in appearance; and comprises an upper structure, a lower structure and a horizontal vibration buffering damping element (5); the upper structure comprises a built-in vertical damping element (1), a limiting element (2) and an elastic element (3); the lower structure comprises an upper frame structure (4) and a lower frame structure (6); and the horizontal vibration buffering damping element (5) is arranged between the upper frame structure (4) and the lower frame structure (6), so that a barrier vibration isolation or shock isolation effect and a layered energy consumption structure are formed between the upper frame structure (4) and the lower frame structure (6). The support has high vibration isolation or shock isolation efficiency, high energy consumption mechanism, high damping characteristic, low inherent frequency and extremely high engineering applicability, the replacement and maintenance are convenient, and the product utilization rate is high.

technical field [0001] The invention relates to the technical field of public buildings and industrial buildings, in particular to a low-frequency, high-load-bearing three-dimensional vibration-isolation and shock-isolation anti-shock bearing. Background technique [0002] Items are prone to damage or damage to components due to strong earthquake shocks or transportation due to road bumps, shocks, and continuous vibrations. At present, it is difficult to effectively remove the combined effects of uneven road surface impact and continuous vibration in transportation, and the carrying equipment is easily damaged or destroyed by the comprehensive vibration. The commonly used methods mainly include airbag support and wire rope fixation, but this The measures are difficult to meet the requirements of equipment vibration isolation / seismic design. In short, the defects of traditional technology mainly include the following aspects: [0003] (1) The damping characteristic is low. ...

AI Technical Summary

Problems solved by technology

[0003] (1) Low damping characteristics

The vibration isolation / vibration isolation technology that only adopts airbag support or steel wire rope fixing has low damping characteristics, and it is difficult to carry out targeted vibration reduction and isolation design according to the working vibration characteristics of the carrying equipment and the actual needs of transportation, and the road bumps during transportation Or the effect of uneven shock and vibration is difficult to be consumed reasonably, which will increase the probability of damage to the carried object, resulting in a higher risk of carrying objects

[0004] (2) High natural frequency

The vibration isolation / shock isolation technology using airbag support or wire rope fixing can meet the requirements of stable transportation to a certain extent, but generally its stiffness is relatively high, and the natural frequency of the system is relatively high, so it is difficult to simultaneously eliminate the impact vibration and continuous vibration of road bumps. Adverse effects, the safety of transported items cannot be guaranteed

[0005] (3) Low vibration isolation / seismic efficiency

The traditional transportation vibration isolation / shock isolation control technology has simple process, cumbersome loading and unloading, and has high natural frequency and low damping characteristics, so it is difficult to effectively isolate the interference and dissipation of external vibration sources under complex road conditions. The energy transmitted to the carrying object and the vibration of large-scale equipment are controlled. The comprehensive vibration isolation effect is poor, and the vibration isolation efficiency is low, which is difficult to meet the design requirements of the item.
