Variable-rigidity and post-earthquake damage-free low-prestress self-resetting damping device
The invention provides a variable-rigidity low-prestress self-resetting damping device free of damage after an earthquake, and belongs to the technical field of damping devices. The variable-rigidity low-prestress self-resetting damping device comprises an outer pipe and an inner pipe with one end movably extending into the outer pipe; four baffles are sequentially arranged in the outer pipe, and a cavity is formed between every two adjacent baffles. Elastic reset pieces are arranged in the cavities located at the two ends, and the inner pipe movably penetrates through the baffles and the elastic reset pieces. The two baffles of the cavity located in the middle are each connected with a displacement amplification mechanism, and the two displacement amplification mechanisms are each connected with a lead extrusion damping mechanism. The variable rigidity and displacement amplification functions are achieved, and the excellent characteristics of no damage after an earthquake, fatigue resistance, long durability and corrosion resistance can be achieved; the initial prestress level of the device is reduced; the installation space requirement is reduced; the energy dissipation capacity of the lead extrusion damping mechanism is enhanced, the defect that the displacement capacity of a reset system is insufficient is overcome, the flexibility of the device is improved, and the anti-seismic performance of the device is enhanced.
本发明提供一种可变刚度‑震后免损伤的低预应力自复位减震装置，属于减震装置技术领域，外管、以及一端可活动的伸入外管的内管；外管的内部依次设有四个挡板，相邻的两个挡板之间为一个腔体；位于两端的腔体内设弹性复位件，内管可活动的穿过挡板、弹性复位件；位于中间的腔体的两个挡板分别连接有一位移放大机构，两个位移放大机构分别连接有一铅挤压阻尼机构。本发明实现了可变刚度与位移放大功能，可实现震后无损伤、抗疲劳性、长耐久性、抗腐蚀性的优良特性；降低了装置的初始预应力水平；减小了安装空间需求；增强了铅挤压阻尼机构的耗能能力，弥补复位系统位移能力不足的缺点，提高装置的灵活性，增强装置的抗震性能。
