Self-powered bridge magneto-rheological damper
The invention discloses a self-powered bridge magneto-rheological damper, and relates to the technical field of energy dissipation and vibration reduction of engineering structures. The problems that the power generation efficiency of an existing spontaneous electromagnetic rheological damper is generally low, and the power requirements of equipment and other elements are difficult to meet are solved. The magneto-rheological damper specifically comprises a magneto-rheological damper body, a plurality of metal pipes are fixed to the outer wall of the magneto-rheological damper body, and a plurality of piezoelectric ceramic power generation pieces are connected to the inner walls of the metal pipes in a sliding mode. Low-frequency and small-amplitude vibration generated by a bridge structure can be effectively converted into medium-low-frequency and high-energy output electric energy, continuous power supply to the magneto-rheological damper body is achieved, dependence of the magneto-rheological damper body on the mains supply is avoided, under natural disasters such as typhoons, the magneto-rheological damper body can still have sufficient electric energy, and the energy-saving and environment-friendly effects are achieved. By detecting the power generation efficiency of the piezoelectric ceramic power generation sheet, the overall state of the bridge can be detected from the side.
本发明公开了一种自供能的桥梁磁流变阻尼器，涉及工程结构消能减振技术领域；为了解决现有自发电磁流变阻尼器的发电效率普遍低下，难以满足设备及其他元件的电力需求的问题；具体包括磁流变阻尼器本体，所述磁流变阻尼器本体外壁固定有多个金属管，金属管内壁滑动连接有多个压电陶瓷发电片。本发明能够将桥梁结构产生的低频、小幅度的振动有效转化为中低频频、高能量输出的电能，实现了对磁流变阻尼器本体的持续供电，避免磁流变阻尼器本体对市电的依赖，在台风等自然灾害下，让磁流变阻尼器本体依然能够有充足的电能，通过对压电陶瓷发电片发电效率的检测，可从侧面对桥梁的整体状态进行检测。
