Vibration-absorption control of multi-degrees-of-freedom system on power flow

  • 摘要: 针对附加动力吸振器的多自由度系统,利用结构导纳理论,引入附加动力吸振器后振动系统的等价结构导纳矩阵,推导了振源输入系统的总功率流、主振系的净功率流以及吸振器吸收的功率流。并且以功率流为控制量,探讨了通过附加单个或多个动力吸振器对多自由度系统进行单模态或多模态控制的问题,揭示了吸振器的控制机理和效果。
    Abstract: In accordance with a multiple degrees of freedom vibration system with dynamic vibration absorbers (DVAs),in this paper, an equivalent admittance matrix and the power flows input major structure and minor structure are deduced on the basis of the theories of structure mobility Furthermore, regarding the net power flow of main vibration system as the controlled object, discussed profoundly are the single and multiple model controls of multi- degrees- of-freedom system with one or several absorbers attached. And the control mechanism and effect of dynamic vibration absorbers are revealed.
