A pendulum three-dimensional display case vibration isolation device with semi-active control

Abstract

The present invention proposes a semi-actively controlled pendulum-type three-dimensional display cabinet vibration isolation device, which includes horizontal vibration isolation components and vertical vibration isolation components arranged up and down, the vibration isolation device can realize the horizontal and vertical movement of the device, the vibration isolation The device has a large bearing capacity, which can meet the requirements of the static bearing capacity of the showcase, and is convenient for the realization of the daily display function of the showcase and the horizontal and vertical shock isolation protection under the action of earthquakes.

Description

technical field [0001] The invention relates to the technical field of vibration control and shock isolation, in particular to a semi-active control pendulum type three-dimensional display case shock isolation device. Background technique [0002] The cultural relics in the museum need to be placed in the display cabinets due to the needs of display. If they encounter factors such as earthquakes or environmental vibrations, it is easy to cause the cultural relics in the display cabinets to become unstable. At this time, the floating cultural relics in the display cabinets may face damage such as overturning and sliding. If a shock isolation device is installed under the display cabinet, the safety of the display cabinet and the cultural relics in the cabinet under the action of an earthquake can be improved. When an earthquake comes, the seismic force is transmitted to the device first, and then the device moves and consumes energy. Therefore, the seismic isolation device of...

AI Technical Summary

Problems solved by technology

When an earthquake comes, the seismic force is transmitted to the device first, and then the device moves and consumes energy. Therefore, the seismic isolation device of the showcase can weaken the seismic force and transmit it to the upper part to protect the safety of the showcase and the cultural relics in the cabinet. The seismic isolation device currently used in museums Most of them are horizontal isolation devices, which do not consider the influence of the vertical force of the earthquake, and a single mechanical device is difficult to meet the requirements of the vertical isolation performance of cultural relics

In the prior art, there is no showcase shock-isolation device that can realize the coordinated work of horizontal shock-isolation parts and vertical shock-isolation parts. Because the showcase shock-isolation device requires a large bearing capacity and high stability, the general three-way isolation The stability of the shock device is low, and the bearing capacity is not high
