半主动控制隔振与非线性能量采集一体化分析
Analysis of Integrate Semi-Active Control Vibration Isolation and Nonlinear Energy Harvesting
摘要: 将采用平衡逻辑控制原理的半主动控制隔振应用到单自由度振动系统中，通过时域、主系统能量耗散和传递率图像研究了该系统的减振性能，结果显示其具有十分优秀的减振性能。将非线性能量采集应用到单自由度振动系统中，通过时域和电流采集图像研究了该系统的减振性能，结果显示其不但拥有优秀的减振性能，而且同时也可以稳定的输出电流。最后将半主动控制隔振与非线性能量采集结合在一个系统中，对该系统在减振和电能采集方面进行了分析，结果显示其不但拥有更优异的减振性能，而且在振动开始后其能量采集装置在较宽的频率范围内都可以稳定的为半主动控制装置输出电能。在两个装置共同作用下该一体化系统不仅拥有更好的减振性能，而且还可以做到完全自给不依赖于外界环境而工作。在条件严酷、维护周期较长的工程环境中有很好的应用前景。
Abstract: In this paper, a semi-active control vibration isolation single degree of freedom vibration system based on balance logic control principle is studied. The vibration suppression performance of the system is analyzed by time-domain response, energy dissipation of the main system damping and transmissibility. The results show that the system has excellent performance in vibration sup-pression. A nonlinear energy harvesting single degree of freedom vibration system is studied. The vibration suppression performance of the system is analyzed by time-domain response and electric current energy harvesting. The results show that it has good performance in vibration suppression and electric current output. At last, an integrate semi-active control vibration isolation and nonlinear energy harvesting system is studied. The vibration suppression and energy harvesting performance of the system is analyzed by time-domain response and electric energy harvesting. The results show that it not only has better vibration suppression performance, but also can output electrical energy stably for the semi-active control device in a wide frequency range after the vibration starts. The integrated system not only has better vibration damping performance, but also can be completely self-supporting and independent of the external environment. It has a good application prospect in the engineering environment with harsh conditions and long maintenance cycle.
