数控工作台动态特性的混沌特征
Chaotic Characteristic Analysis on Dynamic Properties of NC Table
摘要
Abstract
By means of the theory and method on phase- space reconstruction, correlation dimension and maximum Lyapunov exponent from chaos theory, dynamic time series measured from NC table were analyzed. The characteristic quantities as power spectrum, phase trajectories, correlation dimension and maximum Lyapunov exponent etc. were extracted. The chaotic characteristic of dynamic properties of NC table was revealed with several approaches. The conclusion that NC table is a nonlinear dynamic system can be drawn. This research represents basis for the dynamic system identification of CNC machine.关键词
