The Study on an Adaptive Tuned Vibration Absorber and Its Control Strategy Based on Dynamic Mass Match

  • 摘要: 为了研究自调谐吸振器的振动控制策略,分析了系统中吸振器质量及与其耦合的阻尼对振动控制效果的影响,建立了不同的数学模型的运动方程,通过对比分析了在有无动静质量时系统的减振效果,进而对吸振器的控制策略进行研究.为使吸振器的固有频率与激励频率匹配,将谐振时主系统与子系统的相对相位作为评价指标,对吸振器的质量和激励频率进行拟合得到控制方程,提出了一种质量动态匹配的开环控制法,跟踪得到不同激励频率下的控制质量,进而可对主系统的振幅在较宽的频段内进行减振控制.通过实验分析,对自调谐吸振器在宽频带的振动有稳定、快速的控制.
