1基于实验模态分析的集中参数法建模显示文摘利用集中参数模型的建立,不仅拓展了实验模态分析(EMA)的使用范围,还能大量缩减原有模型的自由度并保持结构的动态特性。在对一立铣床进行模态测试以及振型可视化的基础上,采用集中质量、弹簧阻尼单元建立了该铣床的7自由度集中参数模型,并在该模型基础上合成刀尖频响函数及预测颤振稳定域,揭示出机床颤振与振型的联系。与原有测试频响函数的比较表明,该模型准确度较高。杨毅青 刘强 Munoa Jokin 2010振动.测试与诊断2010,30,6:10
2基于正交多项式和稳定图的密集模态参数辨识显示文摘由于正交多项式算法在频响函数模态参数拟合时,模态数目和多项式分子阶次较难确定,无法对拟合过程进行干涉。在原有算法的基础上,通过结合稳定图和模态指示函数,确定了频响函数的模态数目和极点(阻尼及固有频率);在已知极点的基础上,由线性最小二乘方法对留数进行估计。此外,该方法被扩展到频响函数的整体拟合。通过将该方法应用于模态耦合严重的频响函数模态参数估计,并与原有正交多项式算法及商业化软件M E’scopeVES进行对比,表明该算法在避免虚假模态或发生模态遗漏现象的同时,拟合结果准确、稳定,抗干扰能力强。杨毅青 刘强 Munoa Jokin 2010振动.测试与诊断2010,30,4:7

15Limiting Factors for Active Suppression of Structural Chatter Vibrations Using Machine′s Drives显示文摘Chatter vibrations are a major limitation for rough milling operations,leading to productivity reduction,low tool life and poor surface finish.It has been shown recently that the machine tool′s own drives can be used to increase the stability limit related to structural modes of the machine.To damp the low frequency modes,a new feedback loop is added to the classical position,velocity and current cascaded control.The objective of this study is to analyse the limitations of this new chatter suppression technique.Constraints related to the non-collocated control are first studied on a simplified three-mass model and then experimentally demonstrated on a three-axis horizontal milling centre.The industrial integration of the new control loop with sampling time constraints and limited drive′s bandwidth is analysed.After determining the appropriate conditions to use this chatter suppression technique,a cutting test demonstrates that the stability limit can be doubled in the low regions of the stability lobes.Xavier Beudaert Asier Barrios Kaan Erkorkmaz Jokin Munoa 2017Transactions of Nanjing University of Aeronautics and Astronautics2017,34,4:1
