| 摘 要： | 变频单TMD系统是对普通单TMD系统的改进,在普通单TMD系统的基础上提供附加刚度,并通过位移条件控制该附加刚度是否参与TMD系统的工作.变频单TMD系统在不同位移条件下具有不同的频率,具有MTMD(Multiple Tuned Mass Damper)的性能和优点,能减小结构多个自振频率引起的较大的动力响应,显著提高结构的振动控制效果.将变频单TMD系统应用于高层框架结构,分析其动力响应.计算结果表明,变频单TMD系统能有效减小结构的动力响应,与普通单TMD相比,减震效果更为显著.

| Abstract: | The variable frequency single TMD(VF-TMD for short) was constructed.It is composed of common single TMD and an additional spring,and the displacement condition determines whether the additional spring works or not.In comparison with the common single TMD,the VF-TMD has different frequencies in different condition,and it can reduce the dynamic responses which are caused by several natural frequencies,and improve the control effect.VF-TMD was applied to the frame structure to analyze the control effect.The results indicate that VF-TMD can effectively reduce dynamic responses,and the effect is much more obvious than common single TMD. |
