| 摘 要： | 缆索结构系统在外部激励作用下将产生低频谐振,会导致大的振幅而可能有破坏性事故发生,故需要一种有效的方法控制这种振动。本文在考虑拉索抗弯刚度的情况下,在用压杆屈曲函数模拟出实际的振动模型基础上,通过双重迭代计算,求出抑制振动的轴向主动最优控制力,方便快捷地实现了两端固接刚性拉索振动的主动刚度控制。

| Abstract: | Large amplitudes of cables can be induced by low order frequency harmonic oscillations.Then,some destructive accidents will happen,and some efficient control methods will be needed.Considering the bending stiffness of cables,the active optimal control force along axial direction is derived from the bucking function of compressed bars.Through dual iterative computation,the vibration of rigid cable with fixed-ends will be controlled by active stiffness control method conveniently. |
