随机激励下用子结构法分析圆柱-圆板减振器

ANALYSIS OF A COLUMN-DISK VIBRATION DAMPER BY SUBSTRUCTURE METHOD WITH RANDOM EXCITATIONS

  • 摘要: 提出用子结构法分析一种连续体减振器------圆柱-圆板减振器.仿真结果表明: 在不同地震波作用下,圆柱-圆板减振器都可以有较好的减振效果, 克服了常见的弹簧-质量模型在不同地震波作用下减振效果变化大的缺点.

     

    Abstract: The substructure method is used to analyze acolumn-disk vibrationdamper in this paper. The results show that the column-disk vibration damper has an obvious effect for different earthquake-waves and is better than one based on the spring-mass model.
