The performance advantages of using inerter-based network configurations have been identified in a wide range of mechanical structures, such as automotive, railway vehicles and multistory buildings. Mechanical realisations of impedance functions have limitations such as weight and space. To this end, mechatronic devices have much more freedom. Furthermore, the improvement of system performance can be increased by higher-order passive impedance, which can be more conveniently realised using electrical circuits. Also, compared with pure mechanical structures, it is much more convenient to switch between different electrical circuits, and to adjust element values. Hence adaptive vibration suppression properties can be achieved with mechatronic devices. In this project, prototypes of inerter-based mechatronic strut will be designed, assembled and tested. The performance benefits of the mechatronics strut will be studied. Following that, comparison of theoretical and experimental behaviours will be carried out. Effects of system nonlinearities and generator inertial & coil resistance will be investigated. Performance advantages of such devices will be demonstrated for multiple mechanical structures.

使用基于惯性器的网络配置的性能优势已经在广泛的机械结构中被确定，例如汽车、铁路车辆和多层建筑物。阻抗函数的机械实现具有诸如重量和空间的限制。为此，机电一体化设备具有更大的自由度。此外，系统性能的改善可以通过更高阶的无源阻抗来增加，这可以更方便地使用电路来实现。而且，与纯机械结构相比，在不同电路之间切换以及调整元件值要方便得多。因此，自适应振动抑制特性可以通过机电设备来实现。在这个项目中，基于惯性的机电支柱原型将被设计，组装和测试。将研究机电一体化支柱的性能优势。在此之后，将进行理论和实验行为的比较。将研究系统非线性和发电机惯性和线圈电阻的影响。这种装置的性能优势将被证明为多个机械结构。
