| 摘 要： | 提出一种基于刚度分段线性动力吸振器的半主动振动控制策略，通过调节弹性元件的间隙实现吸振器工作频率连续跟踪外激励频率的变化。文中根据基波平衡导出了使主系统近似完全消振所需的弹性元件间隙控制律。数值仿真表明：这种半主动控制策略对于单自由度主系统和多自由度主系统均有很好的消振效果和相当宽的工作频带

| Abstract: | Presented in this paper is a semi active vibration control strategy based on the vibration absorber with adjustable clearance in elastic component. The control law of the clearance for alleviating the vibration of primary system is derived by means of harmonic balancing technique so that the working frequency of the vibration absorber can trace the frequency variation of the harmonic excitation. The efficacy of the strategy is demonstrated by numerical simulations for attenuating the steady state vibration of a SDOF system and a 2 DOF system, which are under the harmonic excitation with slowly varied frequency in a wide range. |
