Viscoelastic-TMD composite multi-dimensional damping device and damping method thereof

Abstract

The invention discloses a viscoelastic-TMD composite multi-dimensional damping device and a damping method thereof. The device comprises counter-force steel sheets, a self-tapping screw which is arranged among the counter-force steel sheets, a first viscoelastic damping supporting system, a second viscoelastic damping supporting system, a mass block and a bottom bearing steel sheet, wherein the self-tapping screw is used for supporting the counter-force steel sheets and adjusting the positions of the counter-force steel sheets as requirement; the first viscoelastic damping supporting system isused for controlling the vibration of the structure in the horizontal direction; the maximum displacement of the mass block in the horizontal direction can be limited through a first bolt and a pre-compressing spring; the second viscoelastic damping supporting system is used for controlling the vibration of the structure in the vertical direction; and the maximum displacement of the mass block inthe vertical direction can be limited through a second bolt and a pre-compressing spring. The device is provided with an adjustable stiffness system and a damping system, so that the vibration response of the structure in a plurality of directions can be effectively stably and continuously controlled.

AI Technical Summary

Benefits of technology

This patented technology describes an improved design for a type of elastomeric material called rubber (R) used in building structures or other applications such as suspensions. These materials have excellent properties like high resistance against compression force but they also absorb much less power compared to traditional hydrogels. By combining these new types of polymer into one body, this innovative product offers better performance without compromising its durability over longer periods of usage. Additionally, by adding certain features to each component separately, it becomes easier to manufacture while maintaining their original quality level. Overall, this novel design improves the efficiency and effectiveness of construction projects involving flexible structures.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of active controllers used on buildings or other types of constructions due to their unique features like directionality (vibrations) generation capabilities and multi-dimensional behavior tunability. Existing designs either lack sufficient energy dissapacity or provide limited flexibility in terms of how they respond when subjected to external forces caused by various factors including gravity waves).
