Abstract

The invention discloses a shockproof suspension shock absorption control method and a device for a museum cultural relic system. Compared with traditional shockproof measures such as improvement of a section of a structural member, improvement of a reinforcement ratio so as to enhance the shockproof ability and additional arrangement of a shock isolation table device, while the shock isolation and shock absorption control cost is not obviously increased and the shockproof ability is effectively improved, time-history analysis and response spectrum analysis calculation are carried out on a museum main body structure-cultural relics integrated system, the earthquake acting force of the museum cultural relic system can be effectively controlled, and huge expenditure is reduced; and as the control method adopted by the system is easy to execute, the cost of the device is comparatively low, large-area promotion and execution of the museum cultural relics are facilitated, damages on the museum cultural relic system by the high-intensity earthquake action can be effectively reduced, and losses are reduced as much as possible.

Description

technical field

[0001] The invention relates to the field of cultural relic protection, in particular to an anti-shock suspension vibration reduction control device and method for a museum cultural relic system. Background technique

[0002] As the carrier of human civilization, cultural relics are non-renewable, and most cultural relics, such as pottery, porcelain, jade, and stone tools, are fragile and difficult to preserve. It is very easy to cause damage under the action of high-intensity earthquakes. At present, the traditional anti-seismic measures for cultural relics are to adopt anti-seismic and shock-isolation methods, which are realized by sticking, absorbing, binding, clamping, supporting and laying shock-absorbing rubber layers, mechanical shock-isolation devices, and shock-isolation floors. The anti-seismic method is usually based on experience and is not based on the analysis, experiment or calculation of the seismic hazards of the placement site, floor, and s...

Examples

Embodiment

[0066] The column adopts 40×40mm, 4mm thick square steel pipe.

[0067] Top beam, middle layer beam, 2 / 3 platform beam, 1 / 2 platform beam, 1 / 3 platform beam, bottom beam, top beam support, middle layer platform support, 2 / 3 platform support, 1 / 3 platform support and bottom The beam supports are all made of 40×40mm, 4mm thick square steel pipes.

[0068] The top platform board, middle layer platform board, 2 / 3 platform board and 1 / 3 platform board are all made of 3.5mm thick iron plate.

[0069] S4. Basic assumptions for calculation of suspension vibration reduction system:

[0070] S41. The display stand adopts a rigid body with a certain mass and no elasticity; the system adopts a steel frame with relatively large rigidity, its component size and area are relatively large, its mass is larger than that of cultural relics, and it can be regarded as a non-deformable rigid body, so only consider its mass rather than its elasticity;

[0071] S42. The connection between the disp...
