| 摘 要： | 从能量角度分析主动式动力吸振器的工作原理,推导出系统的振动响应和主动控制力系数表达式.通过算例,分别绘出了主动控制力系数、主动控制力、结构振幅与外激励频率之间的关系曲线.研究表明,主动式动力吸振器的控制频带范围较宽,主动控制的能量转移对控制结构振动效果较明显,且系统转移的能量随主动控制力的增大而增大. |
| 关 键 词： | 主动式动力吸振器 主动控制力 控制频带 能量转移 |

| Abstract: | The working principle of active dynamic vibration absorber is theoretically analyzed from the perspective of energy,and the expressions of the system vibration response and active control coefficient are deduced,furthermore The curves of active control coefficient,active control force and structure amplitude against incentive frequency are plotted respectively by examples.By comparison,control frequency band of active dynamic vibration absorber is wider than dynamic vibration absorber and the energy from transfer of active control rarie significantly with the effect of vibration control of structure. |
| Keywords: | active dynamic vibration absorber active control force control frequency band energy transfer |
