| 摘 要： | 为了解决航天工程中减振和能源供应的问题，构建了一种应用于航天工程的整星减振和能量采集一体化装置，设计并考察了一种基于非线性能量汇(nonlinear energy sink, NES)的新型非线性减振装置，通过以惯容器(inerter)替代传统的惯性元件以减少负载质量，并在该装置中整合了基于超磁致伸缩材料(giant magnetostrictive material, GMM)的能量采集器.在整星减振的实际背景下对其进行了建模、仿真和分析，同时通过数值计算，考察分析了能量采集器采集振动能量的效果，研究结果表明，在合理选择的参数下，该NES-inerter-GMM(NES-I-GMM)装置能够很好地起到减振作用，同时收集一定的振动能量.

| Abstract: | In order to solve the vibration and energy supply problems in aerospace engineering, an nonlinear vibration absorber integrated into an energy harvester with inerters was designed. The nonlinear vibration absorber was built based on the nonlinear energy sink (NES) in which the traditional inertial components were replaced with inerters, and the energy harvester based on the giant magnetostrictive material (GMM) was integrated into this device. This NES-I-GMM device achieves vibration absorption and energy collection simultaneously. Under the background of the whole satellite vibration reduction, the modeling, simulation and analysis were carried out, and the effects of vibration reduction and energy collection were investigated through numerical computation. The numerical results show that, the NES-I-GMM device works well in vibration reduction and vibration energy collection under reasonable parameters. |
