基于模态参数的背栓式石材幕墙背栓位置识别研究
THE IDENTIFICATION OF THE BACK BOLT POSITION OF BACK BOLT STONE CURTAIN WALL BASED ON MODAL PARAMETERS
【摘要】 为研究既有背栓式石材幕墙的背栓位置识别技术,文中利用有限元模拟与振动测试试验对背栓式石材幕墙进行了模态分析,提出了基于短边模态和长边模态的背栓位置识别方法。结果表明利用短边模态和长边模态特征,沿面板长度方向和宽度方向各设置一条测线即可识别背栓位置,且具有较高的精度。
【Abstract】 In order to study the existing back-bolted stone curtain wall back-bolted position identification technology, the back-bolted stone curtain wall modal analysis was conducted by finite element simulation and vibration tests. Based on the short side modal and long side modal, back-bolted position identification method was proposed.The results show that the back-bolted position can be identified by setting a measurement line along the length and width of the panel with a high accuracy using the short-edge modal and long-edge modal features.
