Annular rubber multi-dimensional damping support
The invention, which belongs to the technical field of bridge structure vibration control, provides an annular rubber multi-dimensional damping support which comprises anti-seismic pins, an annular steel partition plate, a foamed aluminum damping layer and a high-damping rubber annular rubber body. The temperature change causes the movement of a main beam relative to a pier; the anti-seismic pinsextrude the foamed aluminum shock absorption layer and the high-damping rubber body around the anti-seismic pin, and the elasticity modulus of the rubber and the foamed aluminum is relatively small, so that the extrusion force of the anti-seismic pin caused by temperature deformation is relatively small, and the damage to the pier and the support is avoided. Earthquake occurrence, the main beam moves greatly relative to the bridge pier in a short time; the anti-seismic pins can quickly extrude the foamed aluminum damping layer; foamed aluminum has a very strong energy dissipation and vibrationreduction effect, when the extrusion stress of the anti-seismic pin to the foamed aluminum vibration reduction layer is outwards transmitted to the annular rubber area, the stress is weakened, and the high-damping rubber body continues to consume the residual kinetic energy of the structure and release the extrusion stress so as to buffer the impact of earthquakes on the main beam and protect thepier and the support from being damaged more greatly.
本发明属于桥梁结构振动控制技术领域，提供一种环形橡胶多维减震支座，包括抗震销、环形钢隔板、泡沫铝减震层、高阻尼橡胶环形橡胶体。温度变化引起主梁相对于桥墩的运动，抗震销会挤压其周围的泡沫铝减震层和高阻尼橡胶体，由于橡胶和泡沫铝的弹性模量都比较小，因此温度变形引起抗震销的挤压力也比较小，不会造成桥墩和支座的损坏。当发生地震时，主梁在短时间内相对于桥墩产生较大的运动，抗震销会迅速挤压泡沫铝减震层，泡沫铝具有很强的耗能减振作用，当抗震销对泡沫铝减震层的挤压应力向外传递到环形橡胶区域时，应力已经减弱，高阻尼橡胶体继续消耗结构剩余的动能并释放挤压应力，以缓冲地震对主梁的冲击，来保护桥墩和支座免受更大的破坏。
