Triangular hysteresis damping device with negative stiffness characteristic
The invention relates to a triangular hysteresis damping device with a negative stiffness characteristic, and belongs to the technical field of engineering vibration control. The damping device comprises an iron bucket, iron sand, an iron rod, a bucket cover, a rubber pad and a connecting plate; wherein iron sand is contained in the iron bucket, a bucket cover is arranged at the top of the iron bucket, and the iron rod penetrates through the bucket cover and is inserted into the iron sand in the iron bucket; a rubber pad is further sealed on the upper portion of the barrel cover and arranged on the outer surface of the iron rod in a seamless sleeving mode. And the upper part of the iron rod is in bolted connection with the connecting plate. The method can be applied to structural vibration reduction control and has the good and stable negative stiffness characteristic, and the purpose of controlling structural displacement and acceleration response is achieved by reducing the equivalent stiffness of the structure and increasing structural damping.
本发明涉及一种具有负刚度特征的三角形滞回阻尼装置，属于工程振动控制技术领域。所述阻尼装置包括铁桶、铁砂、铁杆、桶盖、橡胶垫以及连接板；其中，所述铁桶内部装有铁砂，铁桶顶部设置有桶盖，所述铁杆穿过桶盖插入到铁桶内的铁砂中；所述桶盖上部还密封有橡胶垫，且橡胶垫无缝套设在所述铁杆外表面；所述铁杆上部螺栓连接有所述连接板。本发明可应用于结构减振控制中，具有良好稳定的负刚度特性，通过降低结构的等效刚度，增大结构阻尼，实现控制结构位移和加速度响应的目的。
