摘要 给出了包含陀螺力影响的旋转梁耦合振动问题的有限元解法,使用的各向异性梁理论考虑了截面翘曲和耦合变形对截面刚度以及对动力特性的影响.单元形函数取为各向异性梁的静态解,以利于提高计算精度.箱形截面旋转梁和某直升机桨叶耦合振动频率的计算结果同参考值相吻合。 The finite element formulation is presented for the coupling dynamic problem of rotor blades with the effect of gyroscopic forces. The anisotropic beam theory used includes the effects of the cross section warping and coupling deformations on the stiffness of cross section and on the dynamic properties of the beam. The shape function of beam element is taken as the static solution of beam, which is helpful to the improvement of accuracy. The computed frequencies of a box beam and a helicopter rotor blade are in good agreement with the reference values, which implies that the present method is correct.
