基于频域内遗传优化和时域分析,对主动调谐质量阻尼器(ATMD)的反馈系数进行了深入研究。通过考察最优化设计ATMD的结构层间位移控制有效性、楼层绝对加速度控制有效性及控制系统冲程和峰值控制力,发现在参数合理和控制力相近情况下,负标准化加速度反馈增益系数(NAFGF)ATMD比正标准化加速度反馈增益系数(NAFGF)ATMD具有更好的控制有效性。
Based on genetic optimization in frequency domain and time-domain analysis, the feedback coefficient of active tuned mass damper (ATMD) is deeply studied. By investigating the effectiveness of ATMD’s structural displacement control, the effectiveness of floor absolute acceleration control and the control of system stroke and peak control force, it is found that the negative normalized acceleration feedback gain factor (NAFGF) ATMD has better control effectiveness than the positive normalized acceleration feedback gain factor (NAFGF) ATMD.
