Dynamic Models and Design of Spindle-Bearing Systems of Machine Tools: A Review

摘要

Machine tools are vital to modern industries. The performance of a machine tool is assessed according to the dimensional accuracy and surface finish of the machined work-pieces, which are closely related to the dynamic characteristics of the spindle-bearing system. The main purpose of this study is to review relevant studies on dynamic models and the design of spindle-bearing systems of machine tools. These studies related to dynamic models are categorized into two types according to the physical components: spindle shafts and bearings. The dynamic models in each category are comprehensively discussed and coordinated. Guidelines condensed from the sampled papers are provided, followed by an exploration of design-related papers. Finally, a conclusion on the analyzed works is drawn and future lines of research are identified.
