Based on the twodimensional 3DOF coupling flutter analysis method(2d3DOF method),the flutter controlling effect and mechanism of central stabilizer on a thin plate section are investigated with a series of sectional model wind tunnel tests.
以针对颤振机理研究而建立的二维三自由度耦合颤振分析方法为理论工具,结合节段模型风洞试验,对薄平板断面中央稳定板气动控制措施的颤振控制效果和控制机理进行了研究。
In order to analyze the aerodynamic mechanism of central stabilizers,firstly,a data processing method for identification of the bridge aerodynamic derivatives in time domain was presented based on three degrees of freedom coupling forced vibration method and 18 aerodynamic derivatives were identified at truss-girder section with and without central stabilizer.
为了研究中央稳定板的气动作用机理,首先采用三自由度耦合振动时域识别的强迫振动法,一次识别出桁架断面在有无中央稳定板时的18个气动导数,然后以识别的气动导数作为输入参数,利用自主研发的NACS软件对矮寨大桥进行了颤振分析;最后通过能量原理对中央稳定板的作用机理进行了证明。
