桥梁节段模型动力试验中刚度的影响

Model stiffness effect on bridge deck section dynamical test

通过试验研究了桥梁节段模型动力试验中模型本身的刚度和支撑位置对颤振导数测量结果的影响 .结果表明节段模型本身的刚度对测得的扭转颤振导数A2 有较大的影响 ,而支撑位置不影响A2 的临界位置 .

Model stiffness and support location effect on flutter derivatives is studied in bridge deck section dynamical test. The result shows that model stiffness obviously affects twist flutter derivative A 2 and support location doesn't change critical position of A 2.
