摘要
阐述了直立细长设备发生风共振的起因。通过共振计算,确定共振时的临界风速,由此提出了直立细长设备发生风共振的判断准则,并根据临界风速产生的动载和弯矩,对设备进行应力强度及疲劳强度校核。
It explained the cause of vertically slender equipment vibration induced by wind and determined the calculation method of critical wind speed during wind inducing vibration of the equipment. Thereby a judgement criterion for wind-induced vibration of the equipment was put forward, and checking for stress intensity and fatigue resistance of the equipment was carried in accordance with dynamic load and bending moment caused by critical wind speed.
