本文探讨一种将实验模态分析和有限元法相结合,识别机械结构结合面动力学数的新方法,以解决大型复杂机装拆不例,难于用实验方法识别部件间结合面动力学参数的问题。用此方法识别了一台摇臂钻床的接触刚度和接触阻尼。
This paper discusses a new method that combines experimental modal analysis with finite element method to identify the dynamics number of mechanical structure joints. It solves the problem of assembly and disassembly of large-scale complex machines and it is difficult to use experimental methods to identify the kinetic parameters of the interface between components. problem. Using this method to identify the contact stiffness and contact damping of a radial drilling machine.
