Abstract:

本发明涉及一种考虑弯曲刚度的斜拉索索力数值计算方法,包括以下步骤:1、对斜拉索的振动进行测量,得到实测的振动频率;对斜拉索索力进行预估,得到预估索力值;2、将斜拉索自身特性值和预估索力值代入考虑弯曲刚度的斜拉索面内运动方程,并利用有限差分的数值方法进行求解,得到斜拉索振动的计算频率;3、计算斜拉索振动的计算频率与实测频率之间的差值,若差值在误差允许范围内,则判定预估索力值即是斜拉索的实际索力值,算法结束;若差值超出误差允许范围,则调整预估索力值,进行循环迭代,直到计算频率与实测频率的差值落在误差允许范围内,调整后的预估索力值即为实际索力值。该方法有利于提高斜拉索索力测量结果的准确性。
