摘要

将两种半主动开关控制策略应用到Voigt型动力吸振器中，并进行性能分析和参数优化。首先，建立动力吸振器系统模型，确定参数取值范围。然后，对两种半主动控制Voigt型动力吸振器进行参数优化，获得最优控制结果和最优参数值，确定了半主动控制的最优策略，对影响优化效果的三个关键参数进行了特性分析。最后，将半主动Voigt型动力吸振器和另外两种传统吸振器对比，用随机激励进一步验证了半主动开关型位移-速度控制策略(On-off DBG)是最有效的控制策略。

Abstract

Here, 2 semi-active on-off control strategies were applied in Voigt dynamic vibration absorber (DVA), and performance comparison and parametric optimization for these two semi-active Voigt DVAs were performed.Firstly, dynamic models of the two Voigt DVAs were established, respectively and their parameters’ ranges were determined.Then, parametric optimization for the two semi-active Voigt DVAs was done, respectively to obtain the optimal control results and the optimal parameter values, and determine the optimal strategy for their semi-active control.The feature analyses were performed for 3 key parameters affecting optimal results.Finally, the 2 semi-active Voigt DVAs were compared with another two traditional DVAs under random excitation.The results showed that the semi-active on-off displacement-velocity control strategy is the most effective one.
