【摘要】 根据调谐质量阻尼器的基本原理引进了虚拟调谐阻尼器概念,并介绍了虚拟调谐阻尼器的几个基本问题,包括:虚实对应关系,虚拟调谐阻尼器的参数设计方法,非纯模态测量的影响,模态溢出,位置优化,同时使用多个虚拟调谐阻尼器问题。使用虚拟调谐阻尼器概念不仅可以方便地借助控制技术的设计工具,并可以设计多个虚拟调谐阻尼器,实现对宽带振动的控制。更多还原

【Abstract】 The concept of virtual tuning damper(VTD) stemming from tuning mass damper(TMD) was introduced.The mathematical model of VTD was deduced based on the basis principle of TMD.The parameters of VTD were designed by deciding the placement of poles and zeros,which was explained by an example.The influence of non-pure modal measurement on VTDk and the modal control spillover were analyzed.The method regarding optimal placement for VTDk was presented.The application of multi-VTD was studied.VTD can be designed by use of commercial control design software.The realization of VTD is more flexible than MTD.It is easy to control the wide-band vibration by use of multi-VTD.更多还原
