主要研究了三维柔性旋转梁的动力特性。采用绝对节点坐标法和几何非线性变形假设,基于一般连续介质理论,建立三维柔性梁的非线性动力学模型;基于摄动理论,结合浮点坐标方法,采用线性化技术,建立柔性旋转梁的振动频域分析模型。对柔性梁自由单摆进行时域仿真,并分析了不同转速下三维柔性旋转梁的频域特性。结果表明,随着转速增加梁的动力刚化现象明显,且垂直旋转平面的模态振型和扭转、拉伸振型所对应的频率会逐渐转化为低阶频率,从而影响柔性梁的振动特性。
The dynamic characteristics of a three-dimensional(3D) flexible rotating beam is studied. Using the absolute node coordinate formulation and geometric nonlinear deformation hypothesis
the nonlinear dynamic model of 3D flexible beam is established based on the general continuum theory. Based on the perturbation theory and the floating-point coordinate method
the vibration frequency domain analysis model of the rotating flexible beam is established by using the linearization technique. Then
the time domain simulation of the free single pendulum of the flexible beam is carried out
and the frequency domain characteristics of the 3D flexible rotating beam at different speeds are analyzed. The results show that as the rotation speed increases
its dynamic stiffening phenomenon is obvious
and the frequency corresponding to the mode shape of the vertical rotation plane and the torsional and tensile modes will gradually be transformed into low-order frequencies
thereby affecting the vibration characteristics of the flexible beam.
