Vibration Control of Cables by Cable-Type Dynamic Vibration Absorbers

摘要

摘要: 研究一类用于控制柔索在谐波激励下的主模态振动的索型动态吸振器.控制索(动态吸振索)与被控索(主索)具有相同的边界条件,并用均匀分布的线性弹簧和阻尼器与主索相联结.因为在相同边界条件下,主索和吸振索具有相同的特征函数,所以在主索的模态坐标下,系统的运动方程等同于具有两质量块的二自由度系统的运动方程.

Abstract: A cable-type dynamic vibration absorber was presented to control cable vibrations of the predominant modes under harmonic excitations.The controlling cable(dynamic absorbing cable)) and the controlled cable(main cable) are under the same boundary condition,and connected by uniformly distributed springs and dampers.Since the both cables have the same eigenfunctions under the same boundary conditions,the equations of motion of the system in the modal coordinates of the main cable are equivalent to those of the two-degree-of-freedom system with two masses.
