摘　　要：从控制力的角度出发,研究多自由度体系下TMD系统的减振机理,并以此为基础建立TMD滤波器模型,研究随机输入下TMD减小结构动力响应的实现途径.研究发现TMD系统控制力的本质是惯性力;当TMD系统参数设置合理时,TMD以一定比值吸收各个频段的外界输入;以线性振动理论为基础的TMD系统,在控制弹性阶段的结构响应时有很卓越的效果.From the perspective of control force,the vibration reduction mechanism of TMD system under multi-degree-of-freedom system is studied.Based on this,a TMD filter model is established,and the way to reduce TMD dynamic response under random input is studied.The study showed that the essence of TMD system control is inertial force.When the parameter setting of TMD system is reasonable,TMD absorbs the external input of each frequency band in a certain ratio.The TMD system based on the linear vibration theory has a remarkable effect in controlling the structural response of the elastic stage.
