摘要 提出了采用动柔度秩2修改实现轴向振动结构被动控制的方法。该方法通过修改结构特性参数,如刚度和阻尼,使系统响应达到控制要求的目标;在此基础上进一步分析了系统响应对修改参数的灵敏度,讨论了振动控制系统的鲁棒性。仿真算例表明,所提出的基于动柔度修改的控制方法能够达到较为满意的控制效果,并有较好的鲁棒性。 A method of receptance modification was presented to realize,the axial vibration control of structures.In the method,modification of characteristic parameters,such as spring and damping coefficients,can make the vibration responses of the structure reach to the excepted requirement.The robustness of the control method was discussed.A numerical example shows that the method can get a satisfied result.
