摘要：
Dynamics characteristics of spindle systems were reconstructed with the changes of spindle speeds and boundary conditions in milling processes, so that the traditional hammer impact experimental modal analysis-driven method was failed to reflect the physical reality. In view of this problem, a five-dimensional model of spindle systems digital twin for dynamics characteristic monitoring was established, the modeling method and operation mechanism were discussed, and the dynamics characteristic monitoring service of spindle system driven by spindle system digital twin was elaborated and it was applied to the dynamics monitoring of spindle systems in milling machining centers. The experimental results show that the model utilizes the interactive fusion of the physical entity and the virtual entity of the spindle systems to accurately obtain the dynamics characteristics of the spindle systems in milling processes through monitoring services, which makes design improvement, operation optimization, fault diagnosis and accurate maintenance of spindle systems possible. © 2020, China Mechanical Engineering Magazine Office.
