In this study, we present an approach to alter the inertance of inerter-based devices, depending on the variation of the frequency of the external excitation. In this regard, we propose a newly developed variable inerter which is able to change the inertance using a versatile type of continuously variable transmission (CVT) mounted on a ball-screw inerter, it is called adaptive tuned viscous inertance damper (ATVID). The proposed device is capable of generating a variable inertance and viscous damping simultaneously contributed to provide seamless variability in its frequency. To evaluate the device performance, damping properties of the ATVID-controlled is compared with passive controlled and uncontrolled single-degree-of-freedom structures exposed to the harmonic ground excitation with variable frequency. Results show an excellent level of vibration reduction in structure using ATVID in a large width of the frequency band of the excitation.

在这项研究中，我们提出了一种方法来改变基于惯性的设备的惯性，具体取决于外部激励频率的变化。在这方面，我们提出了一种新开发的可变惯性装置，该可变惯性装置能够使用安装在滚珠丝杠惯性装置上的通用类型的无级变速箱（CVT）来改变惯性，这称为自适应调谐粘性惯性阻尼器（ATVID）。所提出的装置能够产生可变的惯性，并且粘性阻尼同时有助于提供其频率的无缝可变性。为了评估设备性能，将ATVID受控的阻尼特性与被动受控和非受控的单自由度结构进行了比较，这些结构暴露于具有可变频率的谐波地面激励。
