惯容器非线性减振与能量采集一体化模型动力学分析
摘要
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.
