Symmetrical high-performance viscoelastic damper
The invention belongs to the technical field of dampers, and discloses a symmetrical high-performance viscoelastic damper which comprises two supporting plates, through holes are formed in the supporting plates, and the two supporting plates are connected through a pre-tightening connecting piece; a connecting plate is arranged between the two supporting plates, a plurality of groups of viscoelastic materials are arranged between the connecting plate and the supporting plates, the loss factor of the viscoelastic materials is not less than 0.2, the viscoelastic materials are one of rubber or polyurethane, and the connecting plate and the viscoelastic materials are distributed in a symmetrical structure. According to the invention, a symmetric structure design and a high-performance viscoelastic material (the loss factor is greater than or equal to 0.2) are adopted, so that the energy-dissipating capacity of the damper is greatly enhanced and is more than two times that of a common viscoelastic damper, which means that the damper can absorb and dissipate more energy under the same vibration or impact condition, and the energy-dissipating capacity of the damper is greatly improved. Therefore, vibration and displacement of the structure are effectively reduced.
本发明属于阻尼器技术领域，公开了一种对称高性能粘弹性阻尼器，包括两个支撑板材，所述支撑板材上设有通孔，两个所述支撑板材之间通过预紧连接件连接；两个所述支撑板材之间设有连接板材，所述连接板材与支撑板材之间设有多组粘弹性材料，所述粘弹性材料的损耗因子不小于0.2，所述粘弹性材料为橡胶或聚氨酯中的一种，所述连接板材与粘弹性材料呈对称结构分布设置。本发明中采用对称结构设计和高性能的粘弹性材料(损耗因子≥0.2)，使得该阻尼器的耗能能力大大增强，是普通粘弹性阻尼器的2倍以上，这意味着在相同的振动或冲击条件下，该阻尼器能够吸收并耗散更多的能量，从而更有效地减少结构的振动和位移。
