Results show:(1) coupling of elastic deflections with rigid motions is distinctive;(2) computations of two methods are in good agreement with test data, when rotation angle is small;(3) when rotation angle is large, couplings increase distinctly and the differences between the results of the two computational methods increase;(4) the bending stiffness has evident effect on the coupling, and the coupling will increase with the decrease of bending stiffness;(5) in case of the blade is relatively soft, the calculated values of phase lag and amplitude augment based on infinitesimal rotation will exist.

计算分析表明：(1)弹性桨叶存在较明显的刚性运动和弹性变形耦合；2）挥舞角较小时，两种处理方法计算结果一致，均与试验数据吻合较好；(3挥舞角较大时，刚柔耦合增强，两种处理方法的计算值差别较为明显；(4)桨叶弯曲刚度对桨叶刚柔耦合特性有较明显影响，刚度越小，耦合越强；(5)桨叶如果比较柔软，小转角处理方法计算值相对有限转角处理方法，相位滞后、幅值增加均较为明显，计算桨叶动响应时需引起注意。
