摘要: 综述被动式动力吸振技术的研究概况及其发展。根据结构特点和参数形式将动力吸振器分为单自由度型、组合型、多自由度型、连续参数型和非线性参数型等几种类型,针对其安装于不同主振系、在不同激励下的优化设计问题,总结归纳前人的相关研究成果,梳理当前的研究进展,并提炼今后的发展方向。目前用来抑制主振系单个振动模态的单自由度动力吸振器设计理论已经基本成熟,组合型动力吸振器的优化设计问题也得到了较充分的研究,多自由度型、连续型和非线性动力吸振器的设计和应用成为了研究热点。多自由度动力吸振器能够降低吸振代价,提高吸振效率,其结构设计、参数优化和工程应用等问题都有待进一步充分研究。非线性动力吸振器具有更丰富更复杂的动力学行为,有可能产生新现象、新效应,尤其值得更深入地研究。另外,附加多个吸振器后整个系统的动态响应分析方法也是值得关注的问题。

Abstract: The literature on passive dynamic vibration absorbers (DVA) is reviewed. According to their characteristics of operation, DVAs are categorized as Single degree of freedom DVA (SDOF-DVA), M-SDOF-DVAs, MDOF-DVA, distributed parameter DVA and non-linear DVA. The key achievements on each category of DVAs are summarized and the recent advances are introduced. It is concluded that the designing procedure of SDOF-DVA suppressing one vibration mode of the primary system is well established. Although many approaches have been proposed addressing the optimal design of M-SDOF-DVAs, it is expected that researches on suppressing vibration of structures with multiple DVAs will continue to grow. In addition, efficient and robust reanalysis algorithms for predicting the dynamic response of structures attached multiple absorbers are required. The designing and application of MDOF-DVAs and non-linear DVAs are still open problems. Their physical design, parameter optimization as well as application prospects are much concerned. Moreover, vibrating systems with non-linear DVAs will present complicated dynamics which are drawing more and more attention.
