Design, testing and modelling of adaptive mechatronic vibration suppression systems

在汽车、铁路车辆和多层建筑等广泛的机械结构中，已经确定了使用基于惰性元件的网络配置的性能优势。阻抗函数的机械实现具有重量和空间等限制。为此，机电一体化设备拥有更多的自由。此外，高阶无源阻抗可以提高系统性能，使用电路可以更方便地实现这一点。此外，与纯机械结构相比，在不同电路之间切换和调整元件值要方便得多。因此，利用机电一体化装置可以实现自适应减振。在这个项目中，将设计、组装和测试基于惯性元件的机电支撑的原型。将研究机电一体化支柱的性能优势。然后，将进行理论行为和实验行为的比较。将研究系统非线性和发电机惯性及线圈电阻的影响。这种装置的性能优势将在多种机械结构中得到展示。

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.
