Adjustable damping/vibration-isolating system

Abstract

The invention relates to an adjustable damping / vibration-isolating system which can avoid the generation of overlarge acceleration and displacement reaction in the process of vibration. The adjustable damping / vibration-isolating system comprises a lower supporting part, an upper supporting part, a vibration-isolating unit, two first side plates and two second side plates, wherein the lower supporting part is arranged on a basal plane, and the upper supporting part is arranged above the lower supporting part and used for placing a loaded object. In addition, the vibration-isolating unit comprises a middle plate, a plurality of first supporting rollers and a plurality of second supporting rollers, and the surfaces of the first and second side plates facing the middle plate are respectively provided with a damping element. On the other hand, the peripheral side edge of the middle plate is provided with a plurality of corresponding damping elements for contacting with the damping elements on the first and second side plates so as to slow down the displacement reaction of the middle plate generated by vibration.

Description

technical field [0001] The invention relates to an adjustable damping shock-isolation system, in particular to an adjustable damping shock-isolation system which can avoid excessive acceleration and displacement response during vibration, and can quickly stop after vibration. Background technique [0002] In recent years, natural disasters, such as earthquakes, have occurred frequently around the world. A detailed count of the major earthquakes that have occurred around the world in the past often caused great casualties and irreparable property losses. [0003] Today's human society relies heavily on huge information exchange to carry out various industrial and commercial activities, whether it is through computer networks or general communication systems, it has become the medium of human information exchange today. In addition, basic livelihood systems such as water, electricity, gas, and transportation required for basic social operations also rely heavily on informatio...

AI Technical Summary

Problems solved by technology

Therefore, the frictional damping between the support rollers and the bearing surface is relatively small, so when an earthquake occurs, it is easy to cause the support rollers to roll over a large range on the bearing surface, or even to separate from the upper bearing part and the lower bearing part. , resulting in the complete destruction of the known support system

Moreover, after the earthquake stops, because of the effect of inertia, the rolling of the support roller on the bearing surface will often continue for a long time before it stops, causing the equipment (computer network server or telecommunication exchange mainframe) to be protected to still remain. Chances of being compromised by reciprocating

[0011] Furthermore, if Figure 1A As shown, in the known adjustable damping isolation system, all the components are only combined in a stacked manner, so if the force in the vertical direction is encountered, the components of the known adjustable damping isolation system It is likely to separate from each other due to the force in the vertical direction, resulting in the overturning of the known adjustable damping isolation system together with the equipment to be protected

That is to say, the known adjustable damping isolation system cannot resist the possible damage caused by the force in the vertical direction
