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.
